I have both the powerball and the mini powerball. Both work real well for Billet wheels. I started out 2 years ago doing the wheels by hand with Mother’s Billet Polish, thought it was great stuff, then i got Ardex Metal Mania, that made the shine twice as great. Last year i got the powerball, heres a good pic
left side by hand, right side done right after with the powerball
that was taken last year, since then i ran out of the Ardex metal Mania, i switched to Power Metal and bought the mini powerball, the shine from the power metal is great, 3 weeks later it still looks awesome. The mini helped with the tight spots on these wheels.
