Definitely only spray the two-pot stuff if you're equipped. They ARE worth the effort: better gloss and abrasion. They cure faster and need fewer coats than the one-pot paints/varnishes.

If you are looking for a tough white coating for your hull, consider using a bottom paint designed for trailered boats (powered or sail). Crazy... I know. It only took me 5 years of building to figure that one out. I've had great luck with Interlux VC Performance Epoxy. It's a two-component epoxy-based paint. Very easy to roll and tip, brush or spray. It's epoxy-based so there are no nasty isocyantes like the urethanes. It cures fairly quickly and can be burnished. Only available in white. Nice stuff.
