Powder coating is much stronger than paint and is much less likely to flake or chip. If I remember correctly, it is electrostatically (sp?) bonded to the wheel and then baked to cure it.I have never powder coated anything before. What type of risk is there with rock chips, flaking, peeling, etc. As far as other options, I have seen people do the hydro dip, I would think that and vinyl coverings would wear off or chip and peel badly.
