I have a question about my bottle cap rims... I noticed some white around the edges of the wheel, i took some aluminum pads and scrubed around the wheels and the white spread even more. Im wondering what kinda wheel is this? is it metal? Also, i have some fittipaldi rims doing the same thing, any cure for this white showing on thw wheel? Also, i am in need of some flat bmw emblems that have a diameter of 3 1/16" that is about 1 mm thick. anyone know where i can get them, they are for the fittipaldi's.
