    Repairing nicks in carbon fiber clearcoat finish

    Anybody know a good method for repairing nicks in the clearcoat finish on a carbon fiber frame? They're not anything big - just small nicks on the sides of the seat stays from bumping up against my other bike in the car (now I put the wheel bag between the bikes). I'm just being picky and trying to keep my bike looking as new as possible.

    nicks are easy

    as long as those nicks don't actually cut into the fiber.

    For clear coat nicks, I use clear nail polish - works great!

    ... I guess it depends on how finicky you want/need to be...

    It would be possible to wet sand (with varied grits from say 600 to 2000) and feather the area... then respray with an aerosol clear lacquer...

    I had a Trek 2100 for 2 weeks when I took it in to have the shifting adjusted. When I went to pick it up, there was a big scuff on the carbon fork where it looked like it was slammed into another bike or whatever. I was pissed and wanted a new fork untill they used a very fine buffing compound and the buffed the scuff untill it was completely invisible.

    It was then that I learned to repair anything and everything on a bike.

    If you want a finish that is as hard, or harder than the original clearcoat, I would recommend applying a catalyzed two-part clear finish (like they use on bar tops). You can apply it such that it is slightly thicker than the rest of the finish, then feather it in using progressively finer grits of wet/dry paper (220 through 12,000), followed by polishing and buffing compounds. I used this process on my FSA carbon crankarm, and it's impossible to tell there was ever any damage. I've done the same on the clearcaot on my frame.
