Hi guys. A friend of mine recently had a fall on his bike and one of the Ultegra shifters got a bit scruffed. Nothing structural, just got rid of the clear coat.

Is exposed CF okay? I thought some clear nail polish might be fine to seal it back up as it's a lacquer but I wasn't sure if the acetone would begin to do more harm than good.

Thoughts?

Clean the area with some acetone or lacquer thinner and apply some clear nail polish. If you want a perfect repair, then several coats will be required, followed by careful sanding with 1000 grit sandpaper.

A very gentle sand then clear coat.

Thanks Lachlan. I contacted Shimano and they said nailpolish would be fine.
