Hi Ben. I went to the local auto paint supplier. He recommended an etching primer follwed by a sealer..Then business as usual. Createx told me that their auto air line is compatable with just about any primer. Not trying to beat a dead horse, just been doing some experimenting. I find it interesting that most discussions tend to focus on clearcoat and clear coat issues, however, without a good foundation ( prep, prime, base) any/all clearcoats will fail.. Thanks guys for the input.
