Not a glass expert, but from everything i've read i'm doing the following:
1. Sand the area back or out to the point there the loose gelcoat and/or glass is gone.
2. Fill in with glass and epoxy resin (I'm using MAS)
3. Let dry and sand
4. smooth surface with a coat of resin with coloidal silica in it to create a thicker mix. Used kinda like applying bondo with a plastic spatula.
If the damage is more than superficial, you may need to revert to some of the videos on youtube which show how to fix a hole in the hull. All of mine are small superficial stuff mainly affecting gel coat.
In my case the below water line items i'm addressing this way because I will not be applying gelcoat over it.
Above water line i'm still reviewing cause my understanding is that you cannot apply gelcoat over epoxy resin. and i'd really like to fix the 3-5 small spots on the top with something that I can just buff and not need to paint the area. Any ideas are accepted.
