Craig,
  With mine I used acetone to knock the varnish down with a scraper.  If the build up is not too much, you can spray another light coat over the old one but it adds weight. With the bottom of fuselage open, turn it on it's side and have at it.

I would think so ~~ it does not touch fabric or metal so there is no adhesion problems that I know of.  It worked on mine which is all I know.      W

I ended up lightly sanding it cleaning it with a rag and putting a light coat of polyurathane and it seems fine with negligable weight  gain.I'm amazed that the engine is mounted with such light bolts! Craig

As for me I have used Stitts epoxy varnish and it goes over anything.
