Why would anyone use white gas as a solvent for finish? Beyond the extreme flamability and health issues there is the simple fact it has been designed to be burned and creates a lot of problems in a finishing application.
When solvents down deep in a curing or drying finish warm up they evaporate and if they are encapsulated in finish they create a hole in the finish with the vapor pressure they create when changing phase.
Solvents are bigger molecules than water and those pores they create are big enough for water molecules to run through without even ducking their electrons.
I strongly encourage you to use a solvent designed to be used in finish and if health issues do not bother you just use acetone as it really is an outstanding finish solvent, your liver be damned...
While varnish was as good as finish got before epoxy, it is not even close to as waterproof as epoxy can be.
