Thanks, guys.
I started it today. Got 3 mil polyethylene. I filled the straight part first and will tackle the curved when it cures. Speaking of which, I got an orange blush when I first epoxied the skegs. Started in 60 degree weather, cured in the 40's at night. I was told not to worry, just buff it off, sanding wouldn't be needed. It's in a nearly invisible place on the cat, but it certainly doesn't buff off. I've sanded a bit. It's colored fairly thick.
I don't think I'd be at risk for having this happen again, since the epoxy is curing under the plastic, where no excess moisture can get to it, right? But just to be safe, I closed up the canopy and put a couple heaters in it, one at each bow. Probably 55-60 in there, 45-50 outside.
Ciao,
