I tried an experiment with my G110v2, two yellow Meguiar's polishing pads, and some ColorX and M205, to see what kind of correction they'd give. The 205 came with the ADS special at Christmas-time, so I wanted to see if it gave me that much more correcting power than ColorX worked aggressively. The results were equal- ColorX corrected most swirls but not all. I taped down the center of the trunk, and both sides had some correction but a fair amount of swirls and RIDS still. I'm thinking I didn't work the 205 long enough. Since the search function seems to be broken, how do I know when the 205 has been worked enough?
