Watched a deal on Trucks where he did a set of wheels with it. It takes a lot of buffing to get the surface right before it will do any good. I have the wheels off right now for new rubber. I had buffed my rear wheel two sets ago and it still looks pretty good, without sealing it, even though I neglect it. This has me thinking that after buffing, if you clean the wheels every now and then, they will stay looking good without putting anything on them. I spent about two hours and a couple longnecks last night polishing the front wheel, I'll post some pics tonight on the results.
