Tech Bits and Bites

This month, instead of my usual meanderings I'm dedicating this column to a couple of experts in the field of concours preparation, Chuck Imperatori and Lee Smith.  Both have achieved 100 pt scores in their respective and very competitive JCNA championship classes, yet they use very different approaches as you will read.

Eratta  Before I turn this over to Chuck and Lee I want to correct a few errors in past columns.  Last month I talked about how Jaguars have always been assembled cars.  I misspelled Harry Weslake's last name.  I can only blame my secretary.  She's a lousy speller, but she takes great dictation. Of more import is my oversight in the Suspension Alignment column where I discussed the reasons for using the Ackerman principle in the design of the front suspension.  As was immediately pointed out to me, race cars do not use the Ackerman geometry.  Most actually use reverse Ackerman where the inside wheel turns at a smaller angle than the outside.  The reason for this is that under the high loads a race car experiences the outside tire has a greater slip angle than the inside (it is much more heavily loaded) and its path simulates that of a tire that is turned at a greater angle.  The trick with race cars is to get the best compromise so that a tire doesn't become so overworked that it gives up its traction ability.

 

DETAILING YOUR CAR FOR CONCOURS COMPETITION

by Chuck and Sandy Imperatori

I'm flattered to be asked to speak on this subject. I hasten to add that each time I show my car I learn of new products which are constantly evolving. So, in effect my thoughts are only suggestions or those things that work for me. Every person has their own special formulas, secrets and pet products. My comments are to assist or to be used as a check list. They are not in anyway an endorsement of products. Your own pet brand can be used as a substitute. This is only one method for preparing you car and yourself

1. Personal needs.

Take along comfort items as this will be a very long day. You'll need a change of clothing such as a clean "T" shirt to replace the exhausted one, a collapsible tent or an umbrella to shade you from the sun. You need two collapsible chairs, a cooler for beverages with lots of drinking water. You need a table or picnic blanket. Bring your cell phone or walkie-talkies to keep in touch with your partner to whom you have given your credit card. Above all, be nice to your companion and make this event fun so that they will want to help and come again. If you don't have a partner possibly these comfort items will help you find one. It's at least better than shopping in the super market.

2. Preparation at home.

Start preparing several days in advance as it usually takes longer to prepare your car than you think. You'll make innumerable trips to the automotive store. Do the major jobs at home such as engine cleaning, painting fender wells, fixing chips and dents, cleaning carpets, headliners ..... anything that is really tough. You won't have time at the concours other than to wipe your car off as you try to talk to friends who most likely want to borrow something from you that they forgot. Usually you can get on the field about 8:00AM and it's "rags down" about 10:00 AM. So you have to hustle to set up your tent. In order to avoid the dreaded hustle and to keep in harmony with your partner I go one day early. Make your motel reservations ASAP. You can always cancel. Also, send in the registration form early to help those working the concours. Lastly, keep your head on your shoulders as it will keep your spine from unraveling.

3. Tools

a. Water bucket or canteen and/or as a last resort wet hand towels in a zip lock bag which can be wrung out. Also, bring several dry, clean, hand towels.

b. Use "q" tips with wooden stems as those with plastic stems will melt in solvents.

c. Nylon collapsible garden hose, which can be purchased in a mobile home supply, with quick snap water-jet nozzle and on-off valve which can be found in a hardware store.

d. Pliers to open the water bib or spigot for which the key is probably missing.

e. Small scrub brush, tooth brushes, steel wool pads and disposable rubber gloves.

f. Stainless steel cup for liquids, paint solvents, etc. and paper towels.

g. Dustbuster and pressurized aerosol air cleaner used for computer keyboards.

h. Lint roller for top and upholstery. Indelible black magic marker for quick touch up.

i. Screw driver, scissors, knife, tweezers, bulbs, fuses, blue masking tape and long medical foreceps for those hard to reach places.

4. Cleaners and waxes

a. Blue Coral Dri Aerosol Cleaner for carpets, upholstery and headliner.

b. Simple Green aerosol for rims, spoked wheels, brake dust, degreasing or Turtle Wax 2001 foaming brake dust wheel cleaner.

c. Black Magic Tire Cleaner can be use on any rubber-plastic parts that require a high shine. If it's dull, leave it alone. Don't start something you don't need to keep up.

d. Meguiars Quick Detailer hand sprayer for final mist and wipe. Follow directions.

e. Water. Use under pressure to spray on canvas parts or top. Do not use detergents.

f. Windex. This product is the best of the glass cleaners. Rub briskly with a dry, clean towel.

5. Chemicals and paint

a. Xylol, a medium/slow evaporating solvent or thinner can be used with paints, for tar removal and clean up. Try on an inconspicuous place on the car and to be safe; follow the instructions. It can be purchased at Ace Hardware.

b. Acetone and Naphtha are very strong solvents and highly flammable. Use with utmost caution. Be careful wearing rubber gloves as they can melt onto your skin.

c. CD-2 is an aerosol engine cleaner which I have completely sprayed over my entire engine innumerable times and washed off with jets of water with no problems. There is also an aerosol engine detailer made by CD-2 which really brightens things. Both come as a single package and can be purchased at Pep Boys.

d. Rubbing Compound in liquid form is a must. It can polish as well as being a tar remover, polish chrome and remove over spray.

e. Aerosol engine paint, high temperature in semi gloss black and/or silver is perfect for exhaust manifolds and under carriages or anything else that needs to be painted. If the part is not subject to heat use Rust-Oleum as it really holds up.

f. Sand paper. Wet-dry 240 grit, multi purpose. A small piece cut and glued on a bottle cap can be effectively used to sand down touched up paint pimples.

g. Paper matches after being torn from the book can be used extremely well as a dripless paint brush for paint chip touch up by using the torn back end.

h. Finding a paint match can be done by putting a sample on an inconspicuous place in the engine compartment or trunk area of the car.

i. Leather or such material can be paint matched by soaking a small patch of cloth with acetone and repeatedly wiping a paint matched area; say under a car seat and then transferring that match by blotting the area that needs to be painted. This process may have to be repeated many times to acquire the desired cover up.

6. Miscellaneous

a. XK's Unlimited, (800-444-5247), will overnight to you any part that you require in an emergency. "Dent Tech USA", "Dent Pro" and "Dent Wizard" all can get small dents out of your car for approximately $75.00, more or less. Explain your emergency need and one of the three will come to your rescue at once. They can be found in the yellow pages. As a last resort call your Jag dealer as they also use these firms.

b. Step plates can be covered with heavy, flexible, clear, vinyl taped over the plate to avoid heel scratches and then be removed for the concours. It can be found in fabric stores. Other items which can be damaged such as a luggage back plate in the boot should be removed, provided that chore is a simple one, does not require special tools or real time, and can be easily put in place at the concours.

c. On the field, grass can be removed from the tire treads by using a brush. Then apply Black Magic to the treaded surface and wipe with a towel to dampen the shine. The tires will look brand new and set the car off. Do the windows last.

d. As the judges cannot touch your car they will ask you to open doors, trunks, work the instruments, etc. Wear a glove or use a rag so that your hand does not leave a fingerprint or smudge; which can earn you a dirty deduction.

7. Conclusion.

Yes, you are nuts! But you have to admit you and your partner had fun, met great new friends and saw new places. Most important, you found other cars in your class, had a chance to chat with the owners and most likely gained some great information.

In any event you'll have the cleanest car in your neighborhood. Good luck.

Obsession

by Lee Smith as interpreted by Jerry Nuijen

Lee and Jule’s ‘61 E-Type is the antithesis of Chuck and Sandy’s XJS. It is never driven. It was a total restoration of a car that had not been driven in years, rather than a car that was meticulously maintained from new.

If you are going to win in the class that the Smith’s compete in, whether it is championship JCNA or SCCA, you have to have a car that is used exclusively for showing. It must be a car that was restored from the ground up in the past two or three years and you must be totally committed to preparation or have a professional preparer work on the car for a week before a show.

Lee started his presentation by explaining that he had to get a Ph.D. in physics before he felt ready to compete seriously in concours. Since cars are judged solely on appearance and the way light reflects from a car into the judges’ eyes is what really determines the appearance of a car you must look at a car in all possible lighting conditions. Lee starts by looking at the car in the dark. Once his eyes have dilated completely he turns on a very bright spotlight. Shining the light away from himself at a low angle he can see all the scratches and specks of dirt and other miseries on the surface. This technique is used in many scientific fields and is called dark field microscopy. Lee claims it is 100 times more sensitive than looking at the car in normal light. The reason you must eliminate all scratches, wavy surfaces, and dirt is that you don’t know for sure what the lighting conditions will be when your car is judged. Direct sunlight, cloudy, shady, low angle, directly overhead, light reflected off other cars, all can influence which flaws will show and which will be hidden. To be a sure winner you need to eliminate all flaws.

Cracks are particularly difficult enemies. Lee isn’t talking about cracks in the paint or upholstery that would never exist on a show car; he means seams, crevices and joints that are part of the car’s construction. The midday sun of a concour can bore down into the depths of even the most perfect junction. If there is any wax, dust, overspray or irregularly shiny areas in that "crack" it will detract from the appearance of the car. A particularly tough place on an OTS E-Type is the joint between the top and the rear deck. This seam is deep, collects lint because of the top, and is extremely difficult to keep a consistent width and depth because of the "mobile" nature of a soft-top. Under certain lighting conditions it looks like hell no matter what you do. The best color to have inside a crevice, if it is allowable, is flat black. Flat black won’t reflect any light back to the judges’ eyes. A "sharpie" (magic marker) works wonders.

Another basic physics principle that Lee never fights is gravity. Gravity is always with us and it’s everywhere. You can’t defeat it. Make it work for you. Start cleaning at the highest point of the car and finish at the lowest point. Anything that you remove from the surface of the car is going to move down due to gravity. Work with it. Physics is your friend.

Prepping a car is like doing brain surgery. You must be properly dressed, and follow strict operating procedure. No rings, no belt, nothing that will scratch the car should be worn or carried. Lee reminded us of the little sign,"Unless you’re nude, don’t even come close to this car." Get all tools that aren’t being used to do the prep away from the car. We’ve all heard the story of the guy who put a screwdriver in his back pocket, forgot it, then sat in the car. This, of course, happened at midnight just 8 hours before he had to place his car on the field.

Don’t scratch the car! Scratches cannot be repaired to show standards. "One scratch, $15,000. You need to paint the car." You, or your assistant need to stay with the car at all times to make sure no one, including the judges, touches it.

Top show cars are detailed underneath, even though the judges supposedly don’t look underneath. Good judges will kneel way down to inspect the suspension, the wheel wells, the exhaust system. They will look at the car from a long way off if they know it’s a top contender in its class. The preparation you’ve done underneath can make or break you. Lee has waxed the underside of this car twice since it was finished in 1998.

Originally this car was metallic bronze with tan interior. Purchased from Mike Mueller in Dallas in the early 90’s. The car was in a garage all apart (10 boxes) and covered with spider webs. Rust was everywhere because the car had lived in New England most of its life. Dave Ferguson did all the metal restoration and paint. All the rust was removed and the metal neutralized. Parts of panels were replaced. The sills were reinforced. Lee says, "This car will outlive me." Lodi Plating did all the chrome to Pebble Beach show quality standards (you must specify and pay for this when rechroming) and Al DeLong did all the mechanical. Lee thinks he has $70K+ in the car, but hasn’t kept track lately. The upholstery was done by Rich Elliot. It was actually done twice because when the mechanical work was done it was damaged. Mechanics don’t respect show preparation. Make sure you cover everything that must be done before the mechanical buildup and postpone everything you can until after the mechanical is done.

"Do you want a piece of art to look at, or do you want to drive it? I don’t know how to do both." Lee was candid that he hardly ever sits in this car, let alone drives it. If you sit on the seats very much they will lose their shape. The leather will wrinkle and scuff. Many people restore a car, show it for a few years and when it isn’t winning firsts anymore they start to drive it and restore another car for show.

Lee conducted a long discussion of paint formulations, paint-upholstery color combinations and what constitutes authenticity in these areas. Lee feels that Signal Red with a tan interior is the hot combination for grabbing the judges’ (and the public’s attention). Paint is formulated differently today and the top cloths and plastics and leather dyes are different. It is impossible to be truly authentic in these areas. The group jumped in with facts, opinions and a few fallacies about what is acceptable and what isn’t. If a judge challenges you you need documentation. The original dealer invoice would be the best. Failing that, you can get some information on original color and equipment from a Jaguar Heritage title search.

"You’d better enjoy the competition whatever the outcome because strange things can happen when you are judged. If you don’t win and know you were beaten by an inferior car you just say to yourself, ‘We had a great time, we didn’t win this time, but we’re already thinking about the next show‘."

Lee finished his presentation by showing us some of the tools and materials he uses for prepping. Always have a complete set of spare bulbs. The plywood knock-off tool is a must. You should never apply a hammer to the knock-offs. Artist paintbrushes with long, soft bristles are great for cleaning in crevices. Used dental tools can be purchased cheaply and they work great for cleaning off the harder stuff like "plaque" and "tartar". The dental pick is particularly handy for stabbing recalcitrant judges. "You can get in and out and the judge won’t even know you did it."

Getting serious again . . . wooden meat skewers are good tools of intermediate hardness. As the points wear down discard them. When you buy your upholstery purchase a bottle of the dye that was used on the leather. Lee uses Goof-Off as opposed to Xylol for removing stubborn spots. It can even be used on paint if it is washed off quickly. Goof-Off is available at hardware stores.

Lee never washes his car. Water can get in places and leave a residue that is extremely difficult to remove. The exception is the cloth top. Water, mild soap and a soft brush with a gentle circular motion not only cleans the top it makes it shrink a little as it dries in the sun, pulling creases out and giving it a nice taunt look.

Lee made it all seem so easy you end up wondering why your car doesn’t look like his.

On behalf of the Board of Directors I would like to thank Lee and Jule for taking the time and trouble to share a few tricks of the trade with us and we all applaud the dedication and single mindedness that makes them winners.
