I did use the P21S polishing soap this weekend and the exhaust tips look great. It was simple and mine were pretty gunked up. I actually called our local BMW dealership to find out if the tips that came on my 128i were anodized. Interesting that neither parts or service had an answer to that. The parts guy said the book identifies them as "aluminum look". Since the P21S polishing soap is not supposed to be used on anodized surfaces I hope mine weren't. They do look fantastic now, the polishng soap did the trick (quite easily).
