I bought the Sonus pads a few weeks ago too. I was planning to use the green pad with Meguairs # 9 and the blue pad with AIO. I guess I'd like to hear what other people thing too....
I use the blue Sonus DAS pad with AIO as it doesn't have abrasives. I suppose you could use the green pad falso for more bite but I think that would be better with mild abrasives like SSR1 or SMR.
