DA a spot as if it has been outside and there is no epoxy under the lacquer primer or old paint you will find there is rust on the metal.
Followed Barrys advice and found surface rust on the right rear fender under the primer/bondo and no epoxy. Used a striping disk on that fender and have it down to bare metal now. Took off the primer and layers of bondo and have some metal work to do before epoxy.
Guess I'm not as far along on this thing as I thought I was.
Thanks for all the advice everyone.

deadbodyman It may even wash off fairly ez with lacquer thinner and if that is epoxy underneath the thinner wont hurt it at all.just be sure to give it a thurough cleaning with W&G before spraying anything on it ,there could be a residue left.

Thank you

swvalcon was the car stored inside or did it get out in the weather? If it sat in a garage the whole time I would use a straight board or air file with 180 on it and take it down untill I started to see small spots of bare metal and filler. Then if I couldn't see any surface rust I would just put a coat of epoxy on it.

deadbodyman I'd try sanding the red primer off, being very carful not to sand any filler when you come across it...

Larry123 I did this on my mustang about 20 years ago;stripped the paint, did the body work and loaded up with lacquer primer. Blocked it out and used epoxy reduced as a sealer before shooting the base/clear coat. Itís held up well, still looks pretty good. If yours has been in lacquer primer for a couple of years it could very well have some rust growing under the primer, epoxy wont stop this if its started. You would need to do over if thatís the case.

Epoxy over lacquer primer?

I bought a 36 Chevy a couple years ago and the body was in red oxide primer which I think is lacquer, based on the fact that I can rub it with a thinner soaked cloth and it turns red. There was a lot of body work already finished on the car and I would say it was very well done and seems to be very straight. I am rodding the car and after finishing the chassis work I have now turned my attention to the body, there are a few areas with minor damage that I will fix and I have actually shaved the hinges and door handles. My thought was that I would just block down the primer and then use SPI epoxy to seal everything? I know many will say take it down to bare metal but I really don't want to remove all of someones great work. Can I get away with this?
