My CF bike damaged twice. Once when carrier clamp can loose on 1,000 mile trip and wore thru top layer. Next bike carrier latch failed and lost bike at 40 MPH. Both damaged area looked BAD. I finally stopped crying and patched both damaged areas with nail polish. Couple thousand miles later and nail polish still looks good and frame is still solid and rideable. Note both bike carrier failures were operator error that will NOT happen again.
