Not hard at all. Just make sure its CLEAN, that means any blackness on it take it away (even on the back of the wheel, I used paint striper on the back, and took most of it off, also had a degreser) Then Rub the whole thing with paint thinner, (well after you tape it off, make sure u tape off the valve stem, the tire, adn the center cap) and then get some Dupi-Color High temp paint, and start spraying like it says to on the can (2 light coats and a Medium coat, then how many other coats you need) then lay some Clear (they make high temp clear) over that and wait over night and BAM, its done.
