Hi,
Used my new PC for the first time this weekend on the wifes black 2002 I35. Everything was going well and was wrapping up with the rear bumper when I ran into something I wasn't expecting. The 80 speed glaze wouldn't come off on the lower portion of the bumper. This area on the plastic rear bumper looked horrible. My steps were clay, 80, and then NXT, the only difference for the bumper was I used some Tarminator tar remover first on the area behind the rear tires. It appears that there is some kind of build up that seems to lock up the 80 into it. I tried a few things, Scratch X, dishwashing soap on towel, even a little lacquer thinner but nothing seemed to cut it. Finally tried some Isopropyl Alcohol and that seems to break it down though still not to my satisfaction. Polished again with more 80 and it brightened but noticed if I ran my hand over the area some of this build up would roll up and fall off. These areas will now polish up well but I still have some areas which still seem to have this buildup. Ran out of time tonight but will continue if time permits this week, hoping someone may have an idea whats going on here or may have experienced this before...
