I think there may be a bit of terminology confusion here. Before I came to Canada from
Ireland in the mid 60's, I had regularly used
two-pack polyurethane varnish as a fuel proofer on my free-flight models. It had low
viscosity and cured through chemical reaction
and gave a very tough finish. (Tuffkote was one of the brands.)
I could not find any equivalent finish in Canada and still don't know if it is used
this side of the pond.
The original stuff I used in Ireland would be ideal for covering balsa structures with
lightweight cloth or on its own for use as a
lightweight clear finish, but probably not much use for glass lamination.
