Is Sig Dope fuel proof?? how about AeroGloss or Brodak or any others??
I know Nitrate dope is NOT fuel proof.... does Sig make Buterate Dope?
I don't want to have to buy gallons of full scale aircraft dope.... to expensive!

What's the best choice for use with 10% to 15% Nitro glow fuel?

Seems I used to use Aero Gloss and Silk, , and it always worked well.......
