Powder coating gets cured in an oven so you don't want that with the polycast.

If anything you can cerakote (the air dry stuff) the back side and spray paint the fronts.

But I simply used MRO Seymour gray spray paint for the back sides. Great stuff. Really good color like oem dove gray was.

And then used magnesium color OER brand spray paint on the fronts (after using flex paint and adhesion promotor first) -- a little light in color for my taste as I feel it should be a darker magnesium color. But worked well.
