Self-Etching Primer

The key to getting paint to stick to bare metal is all in the metal prep and using the right primers. Self-etching primer contains a mild acid that actually etches the bare metal to create a superior bond between the primer and the metal. Once the area is coated in self-etching primer, more traditional primers can be used to build out the surface.

    Hi Mark. I look forward to your videos every week and always seem to learn something new. My question: If I apply a zinc phosphate coating on my bare metal (such as After Blast by Eastwood), can I still use a self-etching primer over top of it? Thanks.

    Is it better to apply body filler before or after self etching primer? Will self etching primer work correctly over body filler?

    Mark, I've got some bare metal panels that I've been working on but won't actually get to base coat painting for quite some time (probably months or up to a year). Is the self etching primer something I can spray on to protect it from rust and leave it until I'm finally ready down the road to apply the high build primer?
