I use it a fair amount. Just yesterday, my neighbor wanted her work van (Chevy 1500 van with no side windows) compounded before she gets her company logo applied.
System One outside in direct sun worked great. I spent about 4 hours compounding and polishing (no wax as the logo's will be applied today)
I still use it on some BMW's where the dealer supplied 3M stuff just doesn't work right.
Overall, I think those that bought it and use it have settled in to a comfort zone and continue to toil away.
I didn't even take pics of this work van! I mean a dark green Chevy 1500 is not an awe inspiring vehicle LOL!
