Ething primer is old technology Epoxy is only way to go for superior corrosion protection plus ur filler work bites into epoxy better than bare metal and feathers out better. For those that are skeptical as i was LOL take a piece of metal grind to bare metal tape off one half then spray other half with epoxy, let it dry, wipe whole panel with filler of ur choice, let dry, then bend the metal. The filler will pop off bare metal easily where as it bites so hard on epoxy itll stretch and crack but stay stuck for much longer...........
