If you have deep scratches I would not try to sand them out, scratch has to be super light for me to sand it out, otherwise I use epoxy and a razor blade long edge to fill them in with minimal excess, and then sand flush, at least for my AFS foil, the carbon wing is a lot harder than the Devcon 2-Ton epoxy when it is cured., so it is easy to sand off the excess Devcon epoxy without removing wing material.

Good video for when you give your wing a good bang or scratch. As others have said, it's essential to maintain the original profile.



Light, light scratches can be filled in with clear enamel clear coat and then a super light sand. Matte works well for raw carbon, gloss for finishes like the Moses.

Masking tape is your friend in minimizing overspray that has to be sanded .

This seems clever, the product he uses is softer than epoxy.

I actually did this on an older foil, I don't know why I forgot about it. Thanks for the reminder.

Is there a preferred type of epoxy for this type of repair? I have some general epoxy that I use with fiberglass (long cure time) and I have some 5 minute epoxy.

Make sure the epoxy is waterproof, generic Walmart and HD 5-minute two part epoxies in the dual syringe are not waterproof for all the brands I looked at.
