Just after my car was painted, the body shop had their "saturday" helper buff and polish my car. I didn't see it until about a month after it was done when I went to pick it up. There is dried rubbing compound and polish in just about every body seam on the car. Since they already had the car for about two years and seeing the stellar job they did buffing it, I just decided to fix it myself at home. It just will not come off. I've used a 2500 psi pressure washer, dish soap, ppg pre-clean, etc. Does anyone have a trick for solving this problem?
