Again, as Frostydog and I have stated quite a few times, as long as you're not daydreaming while you're polishing and aware fo what's going on, then you should be fine with the hard BP. I can't remember which car or what area fo the car, but I did have a brief scare once. I think it was up agains a tailight cover that the BP bumped into. It didn't do any damage and I kept moving. You need to be involved when using the
Flex, and not thinking about whether you'll be getting lucky that night or not...
