I used the hyper compound today with my rotary and a small 3 or 4 inch (cant remember size sorry) LC purple wool pad to buff out 2000 3M wet sand paper grit marks. It buffed them out wonderfully with about 1700 RPM and a minute or minute and half working time. I do not know how it compares to the megs but it is a VERY easy product to work with and only needs 3 pea sized drops on the pad to have a minute or two of working time. I would say the optimum line is the best compound/polishing line I have EVER worked with. The 3M 3000 series rubbing compound that I have is probably more abrasive for sure though. I will try the Optimum with my PC this Sunday when I get home and let you know how it goes.
