I don't know if this will help or not....
I just recently tried SSR2.5 to remove swirls & light/moderate scratches and I was VERY impressed. I haven't had much luck with removing defects with meg's products via PC (but rotary does a nice job). I did get some slight marring in a few areas that I worked a few times, but a light polish cleaned that up nicely. I used an orange power pad/SSR2.5, worked the product at 6 via PC (go slow!). Next I applied PwC with a white pad at 4.5 (again, go slow). I topped with EX-P using a finish pad, then souvern by hand. -The results looked nice. I have pictures, but haven't figured out how to size them to post (but eventually will). -Hold tight.
I would compare SSR2.5 somewhere between menzerna IP and menzerna power gloss compound via PC. I haven't tried SSR's via rotary yet, but will soon.
