i have a question on powdercoating rims w/ a polished lip. will the polished lip discolor when it is in the heating oven? the rim is a two piece and i just want to powdercoat the spokes, but not the polished lip. any help will be appreciated.

 

How much is it to powdercoat? What is involved? I have white wheels and am thinking of powdercoating them gunmetal. Is it possible to add a poilshed lip??
