Fiberglass and Gelcoat Repair

Hello everyone. My 79 Ski Nautique is now running and shifting as it should so on the the next step,. I have a few spots on the side of the boat where it got up against a dock. These spots are through the gelcoat but not the fiberglass. Does anyone have a specific brand of product they would recommend to repair these places. I have been told short hair fiberglass should work since I am going to spray fresh gelcoat over the entire boat. What do you boat repair gurus think? I want the boat to be strong and straight. I am also replacing the deck of the floor and a few stringers so I would like to hear opinions on the mats and resins also. Any suggestions would be appreciated. Thanks.

Pete: he mentioned re-spraying the whole boat:

Brewski Here is a link to one of the companies Pete mentioned that has color matched, small repair kits.

I have the pieces for the windshield. I am spraying the entire boat because the previous owner of the boat did some half repairs that don't match. I want this thing to be perfect. I haven't removed the floor yet and I may end up doing all of the stringers if needed. The rear of the boat feels really solid. I would say three baseball sized chips in the gelcoat. I will get pictures when I can. I work a lot and have a newborn due any day, which leaves little time for the Nautique. I sneak away when I can to work on it.

Andrew,
Those are pretty bad but can be repaired. The areas that the PO did a poor job on most likely can be too. Gelling the whole boat is a big job so a repair is an option. I've seen plenty of repairs that you can't tell have been done. As mentioned, the color match is the hard part. For filling the gouges for prepping for gel, I suggest sticking with a polyester filler so there's no bonding issues with the polyester gel.
