I've got SSR 2.5,1, PP, EXP, BH and Natty's Blue. I had less than stellar results with these products using a PC and LC 6.5" pads. I've decided to purchase some smaller 4" pads with the appropriate backing plate after reading about pad size and the PC on here. I was going to pruchase M105 and 205, but thought I'd get the correct pad size first before I purchase new products. That being said, I planned on getting the Orange LC 4" pad, but I'm not sure what others I'll need. Can someone chime in on what other pads I should pick up for my arsenal? The vehicle(s) in question are a Black 05 F150 with moderate swirling/rids and a black 05 c230 benz (i know the clear is hard, just going to try the PB stuff on it first). I also planned on picking up ONR and a few micros. Thanks for the help.
