I have a carbon frame with an integrated seatpost. The saddle sits on a clamp that is meant to secure the saddle on the seatpost and NOT hold the weight of the rider too. I went on a ride and my knees started to bother me, so I went to adjust the height of the saddle and after reading the torque number for the binder clamp, realized I was shit out of luck and was going to either raise the saddle and risk damaging the carbon fiber or let it be and hurt my knees more. I of course chose to raise my saddle. So now I have some nasty gouges where the clamp rubbed the length of the seatpost.
I have spacers in place now to raise the saddle to the correct height but now I have some ugly scratches that are visible just below the binder clamp.
So, the question is, what should I use to keep the surface carbon from cracking more and to seal it up? I have been told to use either paint(not sure what kind) and to use a clear nail polish. Thoughts?
