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