Minor Fiberglass repairs
Get a small fiberglass repair kit like the West System one which contains premeasured resin and catyalst and small tubs of filler material. Also get a tube of gelcoat paste. Remove all loose material from damaged area - an ice pick or small electric grinding tool is good. Mix a batch of filler according to instructions in kit and apply. Finish with gelcoat paste following its specific instructions. This really a pretty easy repair to make.
