370 Motoryacht, my experience with Buff Magic & Pro Polish were similar to yours and Kenny’s. I like the performance of BM and initially the PP, but the PP did not last on the hull. I use a Fein rotary buffer for the BM (may need to slow down based on your advice)and a Portacable orbital for polish. Prior to this I have always used Meg. 50 and Flagship but have been disappointed with black streaks after the rain. The Pro Polish seemed to streak much less but did not have the same longevity especially on the hull which is done once a year. I did a search for Opti Gloss and had no luck, could you point me in the right direction to find more info on that product.
Thanks, Jerry
