well, waht color is stock? black? honestly, i'd juss find a decent high temp engine enamal. or any type of heavy duty spray paint. take the bar, sand it down w/ 180-240 grit sand paper. get some kind of spray can primer, again, heavy duty. spray a couple good coats on it. you may choose to sand the primer or not... your call. once you have it nicely primered, you can spray on the color coat. spray it on in light, even coats. give it a few minutes between coats to "flash" (basic dry). that will prevent runs and overloading which could lead to premature flaking/failure. good luck. if ya have any more questions, hit me up.
