Here's the best I've found. Brush it on, 2 coat's. Looks real nice, seals very well. its very light, and for 8 bucks you'll get a guart that will do more plane's than you got time left on the planet to build.
MINWAX Fast Drying Polyurethane. I get it at Ace Hardware...
Thanks Walt,
Ace is 3 blocks down the street.
