Well if you go to a radiator shop and ask them that question of will paint
slow the dissapation of heat, the answer will be yes. I now have no paint
on my radiators for that reason. I would think that same would hold true on
a brake drum. Probably why the 2000 has finned drums, to dissapate more
heat.
