I often use something other than Aerogloss SS when the piece of balsa is large--like with the BNC 60 on this Estes SLV kit.

A few years ago, someone from the forum sent me a container of Deluxe Sand'n'Seal. It seems to have the same properties as Elmer's or of Mod Podge and requires a lot less applications as would Aerogloss. I don't use it on fins becuse I'm afraid of warping them with this water-based filler.
