Okay so i had a one inch scratch on my passenger side skirt. It was about 2mm wide, pretty wide for a scratch and it was down to the plastic. I decided to use some touchup paint, clear coat then wet sand (2000grit) it smooth. I put 2 layers of paint, 1 layer of clear, and let it cure for a couple days. After 3 days, I decided to give it a light wet sand. I honestly used about 10 medium pressure wet sand strokes and i started seeing black plastic. the small scratch widened to a 4mm patch of plastic.

My other cars (Audi, Porsche, ford and older bmw) never had an issue with wet sanding.

I guess its going in for a respray...a thicker respray.
