Guys:
I am putting in new floor braces and floor and was wondering what do I use behind the hollow cavity of the brace where it welds to the inner rocker panel, the inner rocker panel is ground to a nice clean bare metal surface, I want primer or protect the bare metal to help protect against rust, after the braces are welded in, there is no access to this bare metal. Any ideas would be great, I have been told welding primer,etching primer and epoxy primer. My brain is on overload after all that, hopefully some of you guys have been there, done that.
Thanks Ron

 

Weld thru primer?
