alex you buy dye at your local grocery store not your hobby shop....its Rit,Ritz,Rite(or something like that) Dye....in like 50 billion colors or something...also car paint scratches off too...it's not the paint that cars are protected with it's the gloss coat and at $45+ a quart for decent gloss it's a waste on wheels...now chassis thats another story....attaches is a chassis I did with 3 coats candy red then 1 coat candy yellow and 4 coats candy green and then 1 coat green metallic and 2 part polyurethane clear coat

you can paint wheels they just will scratch off so may as well just use the lexan type paints...i do on my gasers it last quite a while
