Two years and counting on mine, and still have the powdercoat sticking perfectly. I often stuff my shoes into the wheels themselves to get high enough into the engine compartment, and even that does not scratch them. Pretty tough stuff. IMHO prep is everything, regardless of going powdercoat or rattle-can. Mine had absolutely 100% of the chrome removed. Scuffing may not do so well, as the chrome was bubbling-off of the Alu...galvanic-corrosion was the problem with mine. No such issues with paint!
