New boat, probaly from a rock while towing. Just a very small ding in clear coat over metal flake. I would like to fill it in to prevent potential spreading or cracking. It is not something that can be waxed out. What do you guys recommend to fill? Just need a dab of something clear, two part epoxy? I looked at clear gelcoat but I got I lost at all the products, some need gloss additives some need hardeners, etc., also don’t need a quart or gallon.
