Have a friend with a 1965 Mustang coupe, custom painted Seal Grey (porsche color). The car's paint is in great condition, no visible swirls, no hazing just really nice. Unfortunately, the car was left in his shop, underneath a carthat was on the lift above it. The car leaked a tiny bit of oil onto the roof of the 65 and then it sat. After sitting outside for a day or two, my buddy brought the car in and realized that the oil was dried onto the paint!!! He tried claybarring, did not work. When I inspected it, the oil looked as though it has stained the paint! There are about 5 or so little drops on the roof. What's the first step I should take to remedy this?
Try using a solvent like 3M adhesive remover (although I doubt it will shift much). Next step would be a chemical cleaner such as a paint cleanser. After that, you will probably need to switch to try polishing. If the stain isn't gone by then, I am not sure if there is much more you can do.
Nope, many people use 3m adhesive remover to remove tar and other gunk...it is pretty much Tardis. Safe to use. I would try some degrease solution first and see how that works, then some aggressive clay if you have any, then some 3m adhesive remover, then some light sanding, 2500 or 3000.
I would definitely try a chemical cleaner... no reason to eat up clear if you can remove it with a chemical cleaner.
I did not have any chemical cleaner handy so I immediately went to a polish. The oil was worse than I thought, was dripping down the side of the car too. I hit it with an Orange Foam pad + some of the remaining XMT Polish I had left. Took it right out. I'm def getting better at polishing too, the polish broke down much better this time I'll post pics later tonight.
I am glad that worked out for you, thankfully that stuff seems to have come off fairly easily since it could have been much worse! XMT polishes are definately sensitive to working time, too little time means some decent marring/haze but too much time equals a fair amount of dust.
