In the for what it is worth department, I tested a few wb clear coatings to see if they might be fuel proof:
Cabot wb polyurethane, AquaCoat wb hard acrylic lacquer with crosslinker, AquaCoat Table Top acrylic/polyurethane;
Allowing 10 or more days to cure, none could handle 15% nitro 15 minutes lying on the surface, best was Cabot which showed little degradation other than permanent staining, the color of the fuel (pink). The nitro beaded very nicely on the crosslinked lacquer, but was significantly softened in 15 minutes. The acrylic/pu non crosslinked blend softened within 60 seconds.

Just an experiment.
