Outside of using PPP what have you guys used to remove UPGP?? I wanted to polish my hood again and I made three passes with OP/G110/yellow sonus pad and it didn't seem to remove as it was still slick and none of the marring was removed. I used this combo on a portion of my Explorer (still working on it) and it worked great. I think I was able to remove some of it with Opt Power Clean APC but I'm not positive as I didn't try to polish it again.
