Default Re: Bicycle motor coloring?

Yes a black car in the sun will get hotter than a white car, but any kind of paint on aluminum fins will hinder the cooling ability, as it "blocks" the air somewhat from the fins.

Now, using the oven cleaner method would work, as it doesn't paint the aluminum, it just causes it to oxidize and discolor, but you still have raw aluminum.
