A couple of recent threads on this subject got me to thinking more about the possibility of hidden gremlins under the 45+ year primer (Rustoleum, as I recall) on my coupe. I have a spare fender that I am subjecting to my body and paint "skills", so decided to strip it back to the bare metal. Sure enough, my worst fears were realized. How does this happen in a dry storage environment? We have humidity here in the northwest to be sure, but its not as if the car has been directly exposed to it over the years. Looks as though I will be starting from scratch on the body, as well!!
