My bike frame is carbon and it recently got a small chip. It's about the size of a pinky fingernail in size. Should I do anything to treat the chip to help prevent it from getting worse?

Here's a photo of the chip, hopefully this helps narrow things down.

A picture of the chip would be useful (if its just in the frame's clear coat, which it sounds like it probably is, just apply some clear nail polish). Also,… – Batman Apr 11 '14 at 17:25

The effects of the chip depend a bit on "how much" was chipped away. Generally it is always better to seal the chip. I have seen water getting under the protective paint/carbon layer and the area slowly expanding.

If the chip is small I've heard people using nailpolish with good success. For anything a bit bigger, I would probably bring it into a carbon repair place and have them check that the carbon is still structurally sound. They can also repair the chip more professionally.
