yep, that's it.

wow... dunno at exactly what temp they melt the coating, but I know
eastwood sells a kit to do it at home. I do not know if pros use a
different system that uses different temperatures. I _do_ know that it is
_possible_ to re-melt the coating, 'cause that's how some shops get it
off, but again, I don't know exact temps. I seem to remember that you
have to heat it higher to 'burn' it off, but the memory is fuzzy.
I guess I don't drive my car hard enough, 'cause I've never had a problem.
I was going more for resistance to brake fluid and durability. I do know
that I've seen powdercoated m/c frames that showed no signs of a problem
even on the downtubes next to the headers.

like somebody else corrected me on: white absorbs less heat, black
radiates it better. brain fade. but I still doubt color will make a huge
difference. the material might, but it is thin enough not to make a
difference, I believe. if anyone wants the exact specs, let me know, I'll
look up the thickness and temp. specs, etc.
chris, have you not had the brake fluid mess up the paint? painting would
have been much easier...
