Thanks for the tips...this is a 50 year old trailered boat, so any repair won’t be under water for more than 8 hours at a time...the fiberglass and gelcoat are shiny and In great shape, garage kept...I will try a colored gelcoat kit, I am handy with epoxies and sanding and have done some auto body....so I should be reasonably successful! Most of the damage is trailer impact , or other things like that...a few chips where transom transitions to bottom of boat, one big one where boat jumped off front winch roller and an exposed bolt chewed it up...a few rock scrapes on keel from beaching over the years...I don’t plan on ever redoing it, it’s all original and looks like it could go another 50 years...all the chips are untreated so far, so I want to get them filled in and waterproof...if I can color match, even better!
