Re: Porter Cable 7424?
I've used Adam's Swirl & Haze Remover, followed by Revive Polish, and then their Buttery Wax. I have been very pleased with the results, but they now have the Fine Machine Polish and Machine Super Wax. These products are suppose to be even better, and were formulated especially to be applied with an orbital polisher. Of course they recommend the PC-7424, which I couldn't agree more. I plan on buying the new products as well.
Good luck.
