Although I haven’t posted lately, work is continuing. This is my rig for spraying gel coat on the top and electronics box. I bought a new spray gun from a Canadian company (
https://www.thegelcoater.com/) and a used compressor with the capacity to power a spray gun.
My color matching setup. Add a drop of pigment to a spoonful of gel coat, mix, add as needed to a cup of gel coat, dab onto a scrap of hull, then repeat as needed. A 2:2:1 ratio of brown/yellow/black seemed to approach the factory color, but there is a catch to this – when one sands the boat hull even lightly, a brownish “patina” is removed, yielding a lighter color. That didn’t matter for this part of the project since I was overcoating everything, patching the hull would be a different matter.

I was satisfied with the results, but if I had it to do over, I would buy a gallon of gel coat resin (instead of the two quarts that I had, one with wax and the other without), skip the color matching and either spray using a surfacing additive that gives a smoother finish, or just roll on multiple layers of gel coat and sand it lightly. I’d also buy gel coat without wax so that I could add wax just for the last coat.
