Carbon Fiber frame chip/scratch question

Im looking at this mono Q which has a light scuff on the top tube and two deeper paint chips/scratches.

What are your opinions?

The one on the left looks like its just though the top paint coat, revealing a silverish metallic material. The second one on the right looks like its one layer behind that one. But still dont see fibers...

A LBS is going to take a look at it tomorrow.

Those look to be in the middle of the top tube? If so, I wouldn't worry much...

Carbon fiber composites are very sensitive to humidity. When the surface is scratched or otherwise damaged, the risk of humidity penetrating in and eventually causing delamination and structural failure failure. Worst of all, your average LBS won't be able to recognize the moment when your frame is close to quitting on you.

Unexpected, I know: the new and shiny carbon fiber is more sensitive than steel, to moisture, but much less predictable and monitorable.

However, if these scratches are all recent (less than, say, a couple of weeks old), then you have little to worry. Just coat them carefully with the same material the paint is made of.
