What prep work is necessary before I cut & install a reproduction patch
panel? I'm thinking that I should at least prime the backside before I
install it. So before I do, seems like I ought to wash it down - WITH
WHAT? and then go over it once with 80 or 120 grit sander. Would treating
the bare metal with some type of ospho metal prep HELP? OR HINDER?
I know that I will need to remove the primer from the immediate area
where I will be welding, how far should I strip it back? I do have
weld-thru primer for the stripped areas. Thanx again.
