Weld through primer

[AirborneSilva]

Is there a weld through primer that is also self etching (in a rattle can)?

Thanks,
Tony

Tony,
They are really 2 different things with 2 different purposes. Weld-thru primer is a metallic zinc-rich primer that has conductive properties so you can weld thru it (hence them name). It will leave a primer coating intact where the 2 panels are sandwiched together for corrosion resistance.
Self-etching primer has chemicals that give maximum adhesion to metal, it "etches" itself into the metal. It will also help prevent corrosion, however has no conductive properties.

Hope that helps.

Thank you, that does help
