I have the Busch Poliser kit, and use it with a drill. Works miracles! Wheels look at least as good as new, possibly better! Had some scratches on the wheels from when the changed the tires. Took some 1500 grit sandpaper with a D/A sander and sanded the wheels, then polished them with the kit. Wheels look wonderful. I don't have the acid wash product, but will get it next time I order. It will remove stains from the wheels, and leave the entire wheel dull, but after the results from sanding a polishing, I don't think the acid wash will be any problem to polish out.
