I believe the body of the gen is aluminum
so a couple of options.
First, best, but most work. Disassemble the unit and take the case to a local shop that does powder coating. This a bit of a pain and the case would have to be completely stripped of everything: gaskets, seals
, any attached parts
, etc and the powder coating would probably clog all the threads and screw holes in the case requiring clearing all the threads with a tap.
Second option, I have had very good luck using Pettit Alumaprotect primer. It is a 2 part epoxy
primer that bonds to the aluminum
and provides a tough base for an outer coat. I used another Pettit paint
for the finish coat to be sure of compatibility (it was one that they recommended for this application), Pettit Easypoxy one part.
