Marty,i noticed you mentioned in a post above about etching primer. I primed my car with some build primer and sanded it down. While sanding i feathered down to some bare metal. I sprayed some etching primer on the bare metal spots and some went onto the build primer as i did not mask off around every little piece of bare metal i broke through to.Is this going to be a problem when i go to paint (which should be real soon)? Do i need to go over the etching primer with an epoxy primer now and resand and hope i don't break through to the metal again? Thanks for your time
