First off, this is my first official post to this forum, but i've lurked here for a while now. I just became the proud owner of a '75 Deville and didn't know if it would be safe to detail the paint with a PC. I'm not entirely sure if it has a clear coat on it, or if the old paint could take the heat. Its paint is in good condition, and I would like to keep it that way if not make it better. any help is appreciated, i get the feeling that i'm going to be doing it the old fashioned way on a 21' car :nervous2:



and for those interested, i'll post some pics of it as soon as i can, i'm currently deployed to iraq, but i get r&r in september so i'll spend some quality time with my new toy. and maybe my family. maybe.

The PC or any comparable orbital is completely safe for your vehicle. To test to see if it has clearcoat or a single stage paint, apply a polish/compound with a cloth in a small area. If the cloth has the color of your paint on it, it is single stage paint.
 
well hey guys, you're welcome!

so should i use the least aggressive pad/polish combo if/when it needs it?

hopefully it won't need it and i can just put on a nice coat of wax.
 
That car doesn't have a clear coat unless it's been repainted. The original paint would have been single stage; if it's been repainted it could be either.
 
If the paint isn't badly oxidised, you may not need any machine polishing or else very little using only mild compounds.



You probably don't need many of the fancy chemicals that get tossed around here. Something as simple as the OTC Meg's Ultimate Compound would be plenty good if you needed a rubbing compound.



If you are doing multi stage polishing, don't try to get it perfect in the early stages, since you will be removing more paint in the later stages.



If the car has a decent amount of chrome on it, I'd recomend Eagle 1 Nano Wheel Polish as that will look fabulous.



Usually the best routine for single stage paint, is polishing and then applying a glaze (such as Mothers S&G or Meg's #7) and finishing with a pure wax.



BTW: Checkout the online AAFES catalog, as you might be able to order all sorts of chemicals very cheaply through it.
 
Nobody ever really *needs* any "of the fancy chemicals that get tossed around here", just like an audiophile never really *needs* that 500 dollar set of cables, either.



Sure would be a boring hobby without all those fancy chemicals that get tossed around here, woodinit?

Hopefully the paint is in good condition and i can get away with a good glaze and a wax. but if the paint does have swirl marks or oxidation, how deep is too deep? just keep the polish on it until it improves or i see bare metal underneath? if any of you guys know a place to read up on detailing single stage paint, that'd be great. ive searched here, but i don't really know the how to ask the question to get the information i want.
 
I'd look on meguiarsonline.com for single stage paint detailing. Meguiars 80 series polishes do a great job on oxidized single stage paints.

Paint is usually in better condition than you think it is. Often all you need is some light polishing compound to get rid of the surface oxidation and the paint will look much better with relatively little work. Getting every little scratch and swirl out takes more work, and can be costly in terms of paint lost.



It is important to keep the polish moist, so I like to have a sprayer of QD near by and give the surface a spray or two to keep it wet.



but if the paint does have swirl marks or oxidation, how deep is too deep? just keep the polish on it until it improves or i see bare metal underneath?



Based on the number of "Did I burn my paint" posts, that seems to be a popular MO around here. :scared:

I'm going to include a quote from the Malm's wax website which is how I get a sense of the paint's condition before starting up with a machine polisher. If it turns out the paint is cleaning up quickly, then I know I don't have to be agressive with the machine.



Basicly where as in a clearcoat system the pigment is found in a base layer which is covered by a very hard clear layer, in a single stage system the pigment is evenly dispersed throughout the paint.



What happens is that the paint carrier gradually oxidises thus obscuring its entrained pigments. This gives it a chalky look. What polishing single stage paint does is remove this oxidised layer thus exposing "fresh" paint underneath.



What makes this a little complex, is that the oxidised layer can be quite deep, and so you want to budget how much to remove. OTH SS paint systems tend to be quite thick, and the oxidised paint is slightly softer than non-oxidised paint.



One thing to keep in mind is that unlike metal's light actually penetrates car paint (especially SS paint) to some degree before being reflected back out, things like glazes seep into the paint helping light flow into the paint thus giving it more sharply defined colors and reflections.



Use a piece of clean cotton towel, small cellulose sponge or the Kolinsky Speed Waxer Tool. Dampen applicator with distilled water. Now make a test application to determine exactly how much time you must rub the polish into a specified area for best results. This will always vary and is dependent on the condition of the paint. Shake the bottle for 30 seconds. Put about 1/2 a teaspoonful of polish on the cloth or sponge. Firmly rub in 6" circles (ignore this, use back and forth motions) for 60 seconds and limit the application area to about 1' by 2'. Now buff off the polish residue with a dry TOWEL. Examine the paint carefully. If it has reached a high gloss, scratches and dirt were removed, feels real smooth and you're happy with the appearance, polish the rest of the car similarly. If not satisfied, repeat the test for another 60 seconds. Continue these tests until you see no further improvement. The total polishing time needed in the test area should be recorded and used as a guide when polishing the rest of the vehicle.



Do the same thing, except using Meg's Ultimate Compound, and SwirlX, and you should be good to go. I'm also a big fan of KIT scratch out which is very gentle and good for de-hazing paint.
