Yes, the oil based poly works fine, but I switched back to the epoxy. It took a really long time to build up the thickness with the poly, and was not sufficiently hard/stiff for my application. For glassing a wing or fuse, this would be the way to go though.

I found the poly: The water based could be done on the kitchen table over a few newspapers, fast drying, less messy than any other process I've tried, easy to do, and I must mention easy to do. Using ProfLooney's site: http://home.mchsi.com/~jahuntley/help.html , you can get a great finish in no time. Although, the site is down at the time of this posting.
