The first picture below shows what happens when you hit a tire kicked up by the car in front of you at 70mph, it cracked my fog housing, popped out my parking sensor and completely scratched up my car.
after trying out multiple scratch remover, rubbing compound, I read it on the car forum that the film maker recommends using 70% isopropyl alcohol, and it did the trick! after rubbing it for at least an hour in the 140F garage in AZ, the result is below. 90% of the scuff marks are gone, and it will be perfect if I ever remove the clearbra. What a great investment.
