I plan on using it for the entire kayak. Since I'm painting it anyway, all I'm going to do is add more weight and spend more time on it. I expect to use three tubes or so of the PL Premium covering the entire kayak. Each tube doesn't weigh that much. As for the time... I expect my wife won't let me & the 'yak near the water 'til her Sea Bee 13 is built.

I will admit that I'll miss the opportunity of a translucent skin, but it's an excuse to build another kayak. Maybe Jeff's Cast Away 15, with nylon & Corey's Goop...
