This isn't necessarily in regards to pattern planes but you guys seem to have the best and lightest finishes out there.

Last year I followed Mike Hester's [link=http://www.customairframes.com/caaforum/showthread.php?t=93]technique[/link] to glass a small balsa cowl but now I want to do an entire plane.

My question is do you guys feel this is any heavier than film covering or if done right it should be the same or at least very close?
