Primer/Paint Small Areas in Engine Bay
 

I'm in the process of adding reinforcements to the rear shock towers and replacing the rear sway bar brackets in my guards red 930. But before I weld in the gussets and sway bar brackets can anyone give me pointers/suggestions on what to apply to surfaces that will be trapped (between gussets and body) and what type of primers and paint to apply to these small areas? I researched zinc weld through primer but seems it's not effective against corrosion? I was hoping that a simple 2K spray can paint along with compatible primer is all I needed for small areas of painting guards red color within the engine bay. What have others done in this situation?

I use upol weld thru copper primer. For your gussets some 2k epoxy primer, let it flash then either your basecoat, clear or single stage over the epoxy.
