Ever bought a set of 2nd hand aluminium alloy rims and decided you want them a different colour? One popular solution (besides painting) would be to powdercoat the rims to the finish you are looking for.
However, this solution may be more risky than you think. Possible wheel failure (please see pics attached) is a risk you may face due to reasons such as:
1. sandblasting or glass-bead blasting of aluminium penetrating the surface of the material to begin crack initiation.
2. Heating aluminum alloys above 275
