2004 BMW 330i. I've done this one a few times now but this time was mostly because a board on the freeway was kicked up by a truck and hit the BMW on the hood, part of the front left fender and door. He wanted to see if I could buff it out enough that he could live with it instead of having it repainted.
I stopped by his house last weekend after finishing another job to take a look and tried out some
DACP by hand on it and I was able to make a noticable improvement but knew immediately not all of the scratches could be removed. He said he could see a difference and was aware not all could be corrected without a repaint and asked me to go ahead and schedule a detail.
Before (although after some minor correction by hand a few days earlier with DACP):
After polishing with Optimum's Hyper Compound using a burgandy
Meguiars cutting pad (definitely left some hazing) and Optimum Compound using a yellow LC cutting pad (removed most of the hazing). Obviously not perfect but a noticable improvement.
I then went over the whole car with
Meguiars #83 DACP using a Meguiars polishing pad and then #80 Speed Glaze, again using a Meguiars polishing pad. I went with Meguiars over Optimum because I wanted the filling properties I get with the 'trade secret' oils both Meguiars polishes contain. Polishing wasn't going to completely remove the scratches so I filled (mostly) what was left. I then topped with Meguiars #16. Sorry no after shots of the hood in the sun-about 3 hours had passed and I couldn't get a good angle. Definitely improved even more from the heavy polishing.
Oddly enough, though I had done this car a few times, I never had full sun to put the car in and realized for the first time the paint was metallic!
I also suspect the hood has been repainted at some point, the paint was noticably harder and took the heavy compounding on the scratches to also remove the halo swirls while the rest of the car responded well to DACP and #80.
