: Just curious about which water-based polyurethane you used. I've used the
: system 3 product on all 4 of the boats I've built and have been happy with
: the results...after I thinned it 1 part water to 1 part urethane. Also,
: humidity here in Ohio seems to be high enough for the stuff. I don't know
: how well it would work in a desert climate. Have you tried marking it up
: with permanent marker then sanding it with 220 on a ROS? The marker lets
: you know when it's been sanded down without going to far.

I haven't tried sanding the whole thing down. I found sanding between coats bad enough during initial coating because the polyurethane is so tough. The marker idea is a good one, except I need to get the whole lot off, so I kind of need the marker to be between the epoxy and the polyurethane. The brand I used is sold in Queensland here in Australia and is called Aqua-Cote.

Thanks,
Steve
