Hoping for some guidance on how to fix a nick in a composite whirlwind 300 prop. It's on the trailing edge of one of the blades and was found during the most recent 50 hour inspection. It's not large, but you can definitely catch it with your nail. My first thought would be to just add a drop of epoxy to it and try to sand it back to flush. I am worried that my sanding will leave a large, very noticeable area on the blade unless I sand it up to 5000 grit and then polish it. Anyone have any experience?
