i got my optimum polish last week...so today i wanted to see how well it works. i only have this craftsman buffer and i tried both of the bonnets it came with. the blue one in the picture and a regular terry cloth one. both yeilded minimal results in removing swirls and scratches. i also have a 10" buffer...but im not even going to bother trying that out. it still looked the same as having just a few layers of NXT applied. i think ill just have to buy a PC soon. the detailing place where i work at uses similar makita and some other repuable power tool brand...and the cars they do come out flawless. i think i may use what i have in the garage for now. will the pads and all that stuff fit on other brand buffers that are similar to the PC?
