The orange Excel Propel pads on a PC with OP at 6 are great and leave no marring so far even on dark cars, haven't done a black car yet. With PB 2.5, it leaves some marring maybe, but not too bad. The yellow pad I'm not real comfortable with so far. It leaves a little marring (maybe) and the pad and polisher moves around a lot for me on speeds above 5. But maybe I just need more time with it.
For tough to get swirls and imperfection, I am gonna try the Optimum Hyper Compound. I have heard it works pretty good and I am thinking it will do the trick on stubborn swirls with the orange pad.
Has any one ever tried using PB2.5 and OP polish combined to reduce dusting. I was also thinking of mixing OP polish and Hyper compound to get something in the middle. I really like OP polish so far as a little goes a long way and you can work it a long time. I also like Megs speed glaze too.
