If referring to lacquer.... It is readily available just about anywhere. I only want to use it to seal the fabric in place of dope. No or very little shrinking is necessary as the fabric will take care of that before doping or "lacquering" as it were.

I can't find it now but there was a web site that was selling waterborne products that take the place of dope. From what I gathered it was a "two part" urethane product. Maybe that is the way to go as i intend to use an automotive urethane clear over the top to fuel proof everything.

As far as lacqure not being fuel proof, I painted several planes back in the early 80's using DuPont automotive lacquer and that paint was fuel proof enough that I never had any issues unless I soaked the plane in fuel and let it set. Incidental spills were not a problem.
