I use a foam brush and soak the whole air frame with balsarite for film. The Balsarite for film is very thin as it is. Are you sure you have the stuff for film and no the one for coverings with no adhesive? The Balsarite for fabric is thick like Sig Stix-it.

I learned I could use the cheap hairspray too. Just read the labels and look for lacquer and you should be good to go. I have used it on a small plane and it works pretty well.
