I've only used CCS blue pad on a GG6 and it works but I don't really like it and feel there has got to be something better. I would like to hear what everyone else uses and what you like about it.
I have Sonus finishing pads, Lake Country finishing pads, Meguiar's finishing pads, CMA finishing pads, 3M finishing pads... I have no particular favorite, I use them all!
Six months ago I would have said crimson hydro tech foam pad. Now after much experimenting Megs DA MF finishing disc. I can run it at slow speeds with amazing results. Cleans easy and like MF towels you can use over and over again. I don't think the full potential of these discs have been realized at this point. I haven't bought a foam pad since.
