Sand paper for carbon fiber scratch repair

I'm repairing some scratches in my carbon fiber and I was wondering what grit sandpaper should I use to sand it down. I was thinking maybe 400.

It would all depend on how deep a scratch you are talking about you could sand thru the clear (Not Good) but it is possible but 400 will not do you would need to use lots of water and 2000 micro paper.
Or take it to someone we have a few good places in So. Cal. for CF repair it would be the safer route to take.
Or better yet leave it alone.

Wet or dry, used in Auto repainting is not sand, garnet grit, paper .

and you need to do wet sanding when the screen-size # is getting sufficiently small.

If the bike is shiny then after you sand the scratch you have to polish it back or you will get a dull area where you applied the sand paper.

Get paint polisher for that.
