So I'm getting around to repairing some nicks and scratches on my bumpers and side skirts on my 02 GTI. I have some touch up paint and I need to get some clear coat. To repair chips and deep scratches they obviously need to be painted over in layers over time, days I've heard, and then clearcoated and sanded over to match the smoothness of the surrounding paint. Will 2000 grit wet sandpaper damage the unharmed paint surrounding the touch up paint?
