Carbon Fibre Hood Repair

[JamesS]

I recently bought a used carbon fibre hood. The issue is that it has several areas where the gel coat has cracked. I plan on painting it body colour, but am concerned that the cracks in the gel coat will eventually crack the paint on the top coat. My questions are
1. Can I sand down to bare carbon (or is there any way to get there)?
2. What are my options for a long term fix? It doesn't have to look pretty and I don't care about the carbon weave.

Here are some pics



Thanks in advance

You can feather out the scratches with a da with 80, fill with putty, sand with 180, feather out with 320. Prime then paint.

Wouldn't a really thin mix of epoxy resin be better for filling/sealing the cracks than putty?
