Default Glassing with Water based urethane

I am going to try using MinWax polycrylic urethane as the fill coats on a glassed wing instead of West Systems epoxy. I have two questions....

1) after applying, do you squegee off the excess like epoxy or does it dry two fast

2) do you wet or dry sand this stuff


Thanks.

I used this method on a 1/4 scale Cap-21 with good success. It dries slow and I just brushed it on and left it to dry. Sanded it with 220 dry and put 2 additional coats on sanding each one, came out real nice. I will be doing a Ziroli texan the same way here pretty soon.

Thanks.... Where did you get the plans for the CAP 21? I've always loved that plane and would like to build another one day.
