I have used the Balsarite under film (both Mono and Ultra) on two planes. I was useing some older covering and I wanted to ensure that it would stick. The Balsarite goes on quite thin and dries very quickly. It does seem to give the adhesive more "bite". I will probably use it in the future. As far as using it on top of the film for overlap, I haven't tried that, but I think I will experiment a bit.


One word of caution! Check the able, this stuff contains some NASTY stuff. You need PLENTY of ventilation with it. I took it out to the garage to do mine.
