I would agree that getting an actual buffer from the start would have been a better idea. I used 2 older drill motors to start and both wore out quick (were probably on their last leg) and only did about 20 square feet total, I bought that $50 motor (stated in the previous post) and it lasted down to the last 5 square feet before the trigger and speed adjuster finally shorted out altogether?!? I went out and got a nicer motor this time just to finish up that last little bit of polishing since I needed a new drill to use as a drill. If I did it again, it would have been a better investment to get a DeWalt polisher (hindsight is always better). Anyway, I am happy to be complete at least having to polish 30 year oxidation, now just the yearly upkeep.
