I painted the interior skins/bulkheads on my first RV with Dupont Veriprime, but switched over to PPG DP50LF Epoxy based primer for the RV-4 I am building based on others recommendations.
After using the PPG epoxy primer for a while, I find that it is a lot more easily scratched and comes off more easily with paint thinner/solvent. I have to be a lot more careful with it than the Veriprime. Supposely it seals the aluminum against corrosion a lot better than Veriprime, but it doesnt seem to stand up as well. I was going to paint the interior of my cockpit with it and just leave it. Now having second thoughts.
Am I doing something wrong or is there a hardener you can add to it to make it more durable?
