I tore up a SOLO wool pad in one car's worth of use. Hopefully they'll replace it, as it was 15 bucks at the body shop supply
.
Their foam pads are nice, but I'm not sold on the one liquid system. I got to demo it, but honestly I find the same failings that I find with all of the pad dependent polishes out there - it doesn't cut fast and hard enough for me on a wool pad, and it doesn't finish quickly enough for me on a foam pad or perfectly on all paint types.
It fills someone's need for sure, but not mine.
