[MikeD930]

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?
