u can always powdercoat it. if it were me i'd clean it up real nice(like 320grid sandpaper or something) and buy that high temp paint to be on the safe side and paint it w/e color.
Easy mod.
I used some red-metal flake that I picked up at autozone. My wife sanded the bar down while I was working on the car, thne I just put 3 coats and reinstalled. There were a few runs, but I don't really car that much and it looks pretty good.
I'm at work, so sorry, no pics.
First I traded my red P5 strut bar for a silver MSP strut bar. Then I used the exact same paint that I repainted my body with. Did the center of the silver strut bar with laser blue mica with blue pearl.
