The thinner/solvent recommeneded is ethylene glycol monobutyl ether. Butyl Cellosolve brand? Can one not use antifreeze? Which of course is ethylene glycol. Why asking? I am new to using water born products(GF brand). Stain over large table top more difficult with this water product compared to the solvent base which I have decades experience with. Have not used antifreeze for this purpose, just curious as certainly more readily available in the garage and cheaper.
