I recently had a co-worker approch me to do a paint corrction on his F150. I looked at the truck and decided that it needed me. This thing was trashed, even after I worked for 8 hours it was still in need of a new paint job. However it did look 300% better. The rims on it had never been polished, or cleaned properly. They are straight aluminum, very dull, just white finish. The Power Ball helped tremendously. It saved me lots of time, even though I did go back and redo everything by hand, that thing helped alot. I know alot of u guys have tried it and hated it, which made me not want to buy it, but I took a chance and it worked out. Anyone that is thinking of using one, just remember one simple tip. If your rims have lots of sharp edges or holes and such, it may not help you much. But if your rims are smooth, with really wide openings it will save time....but thats just my opinion (and i am far from an expert on anything!!) I just wanted to let everyone know my take..:thumbup::thumbup:
