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.
