Paul,
Before you expend too much time and energy, review this topic from last November.

Read the whole thread, but in particular read Brett Buck's contribution in Reply 17.
I am curious why someone would suggest using Balsarite on plywood. My experience with $cote is that it seems to stick to plywood every bit as well as to balsa, if not better.

Indeed, read entire thread. We have a mere difference of opinion on the value of original-formula Balsarite thinned 50/50 with acetone. I stick by my comments on above noted post and in the Stunt News article where I detailed my techniques in using film. There have been no changes of consequence since publication of that article.
The difference, desired by myself, maybe not needed by others, it that my procedure--stolen from the RC Pattern guys--results in MonoKote being a permanent laminate to underlying wood. It cannot be removed.
Ultimately one must test various ways on some relatively large scraps of wood. Pick what you like and stay with it.
Sig "Stix-It" does indeed work the same as Balsarite, although I actually use the latter product, simply due to familiarity with the product, a known thinning ratio. Again, your choice.
