: While the clear vinyl works, it's not abrasion resistant at all, so
: you have to be very careful using the boat covered with it.

I'll second that. I used some on my daughters' first kayaks. The skins lasted about two seasons and that was being gentle with them. I think a single layer of epoxy-coated 4oz Dacron would be tougher...

It's too bad that clear urethane Blue Hawaii uses on their clear SOF's isn't available. It's supposed to be a lot tougher than the clear PVC.
