I have been asked to strip and repaint a 76 coupe that has been oil sprayed for rust prevention. According to the owner the car has been oil sprayed a few times over the last 5 to 6 years. The entire car has been sprayed from underneath, the doors and door posts have holes drilled to allow them to be sprayed without dismantling any upholstry. The car had been clear coated years ago by a shop that did not sand the existing paint, thus the clear is now falling off in several areas but not enough to believe that it could be removed in any other way than by a complete chemical stripping. I have chemically stripped many cars, including several Corvettes. I am not worried about the stripping process but am concerned that the body panels will have some random oil saturation problems which may cause primer & paint problems. Has anyone of you had to deal with a potential problem like this? Am I over concerned? I have never had to deal with this before but did have to repair oil damage to a hood & firewall of a 64 Coupe damaged by excessive blow by. That damage may have been amplified by the fact that the oil was hot. It did a lot of damage and I don't want to get into an unfixable nightmare with the 76 or it's owner. Any advice will be appreciated. Thanks, Larry Ingram, Ottawa, Canada

Re: Oil saturated body panels
That is the weirdest thing I ever heard. If you wanted the paint to last I would clean all the oil off with laqure thinner. But that would be a real job to do on the inside of the doors, etc. How foolish to spray oil on the underside of the body pannels. The laqure thinner may infact transport the oil deeper into the fiberglass. If you wash it several times it might come out of the pores and have less chance to migrate through to the other side. I would guarantee the paint job for more than a week. Just my opinion though. -
Re: Oil saturated body panels
My guess is that the oil was successful in keeping the body of that 76 from rusting?
Why on earth would an owner spray body panels? This sounds like a nightmare - always wondering if the panels are saturated and whether or not the paint is going to start lifting.

Re: Oil saturated body panels
Run away from this job as fast as possible! You will regret ever sarting it if you do. Any oil saturation will be almost impossible to fix.Comment

Re: Oil saturated body panels
I went through some of this when I painted my 69, but it was mostly the hood. So much oil came out of my hood after I removed the paint that it ran down and made a puddle (it was leaning on the wall). after wipeing and wipeing with laq. thinner I noticed it was coming through the same pores in the glass. A vette body man solved the problem by using laq. thinner in the sun and then moving to the shop where he mixed up epoxy primmer and wiped one more time right before spraying. This locked in the oil and forced it to go to the inside of the glass instead of toward the painted side. The glass surface was sanded with 180 just prior to p*******. Hope this helps. DavidComment
