Does an epoxy primer ever go over a self etching primer? (Dupont products) I am almost done with my body work and was going to spray everything with some vari-prime self etching primer, then some 2-K and eventually sealer or 2-k sealer combo. However I understand epoxy primer is considered more durable. Car was brought down to the bare metal. Car is indoors and will stay that way until top coated hopefully this fall. So...epoxy primer or not?
