How deep is deep? If its gone through clear coat then even wet sanding won't help.

Some of my mates swear by wet sanding with 2000 grit whilst others use a machine with a heavy cutting compound. I've got a variable speed polisher and use g3 (iirc - don't think it's g6 - need to get some g7 for celly paints) and g10 to finish it. Want to get my mits on some megs 205 and 105 and see what they're like compared to what I've got. You can get different heads for different cutting/finishing levels.

Looks quite good for your first attempt - bet your arms hurt from t cutting can get a deeper shine from a bit more work (I spent 9 hours on my escort and I'm still not happy)

Keep it up!
