Well, my Jetta is lowered and I backed into a small ditch and my sideskirts rubbed in some gravel. Well, it looked pretty bad on the bottom. I looked at the paint and determined that it didn't break through the clear. So, what I did was take some 1000 grit sandpaper and wetsanded wherever the rash was until it disapeared. Then, I took some 3M heavy duty rubbing compund and put it on a rotary buffer with a wool pad. That took the marring away caused by the sandpaper. Then, I took some 3M Imperial Microfinishing compund and hit it with a rotary to bring the shine back. I finished with the machine with some Megs #9. By hand, I added Klasse about 3 days later and then 24 hrs after that, I added some P21S. They look as good as new.
However, if the curb rash broke through the clear, you will need to take some 1200 and the reclear. If it broke through the clear and the color, you will need to repaint the skirt or at least add some touch up paint, hit it with some 1200 grit paper and then follow the directions above.
