What colour and how you doing it?
Black at the moment , im tempted with blue though since it seems to be a bit more glossy than the matte black option
Just spraying it on the wheels , you can buy cans of the stuff and apply a few coats using about 3 cans per set of wheels with about 3 coats of stuff, then when your done with it just peel it all off.
Im doing it as i always wanted black wheels and for £10 a can cant complain.
Im getting a create your colour kit plus the 799 shine coating. Im thinning mine with toulene and spraying it with a gravity fed spray gun
