My wife's board sustained some minor damage - my fault, oops. It's fiberglass and I'm fine with repairing that. However, I'm not sure what most people use as a finish.
To the extent possible I'd like to avoid toxic materials as much as reasonably possible (fumes/vapor) yet also achieve a nice smooth finish. Are there brushed on finishes that would satisfy my needs? I'm quite OK with wet sanding as needed. I don't have a place I can spray it indoors and as the weather gets cooler I'm concerned with it drying sufficiently.

Have you thought about using re- deck ? A roll on grip to re grip boards that have worn out non slide.

I should have given more info. I accidently put a 3/4" diameter hole in the bottom. While building an outdoor rack to hold multiple boards, I dropped a darn pipe clamp and of course the end of the pipe landed on her board. The fiberglass repair will be easy enough. When I received a (different) board (Bic Go) that was shipped in a double layer of cardboard, it arrived with a 2"x1" gash along the edge. Fixing the fiberglass was easy. When that was done, I just squeegeed on some epoxy gelcoat over the spot and wet sanded with 400 and then 1000 grit paper. Looked great. However, her board (actually an SUP board) has issues with its bottom finish having many penny sized flakes that came off so I need to sand down the entire bottom and refinish it. A spot repair won't be adequate.

Spray paint and and possibly primer?

I used Rustoleum automotive enamel paint on the deck of my Goya Bolt (search to see my writeup), and clear coated with same, has held up great, but it does off-gas for 7 days while it is curing. I put it in a spare bathroom and ran the exhaust fan 24/7.

Sounds like maybe you should do the repair and then take to a local shop to have the bottom spray painted.

Might be easier to get a new wife.

Id be trying to find a paint that off gasses for at least three weeks minimum.

Yeah. It's best to run a 50 000 gigawatt heater in the bathroom at the same time too. You want it running for the full three weeks to get the paint to full cure.

Jealous that I successfully painted my board and the finish is holding up perfectly! Hey, if it is over your capabilities I can understand
