shelf life of spar varnish
So all the needles I sealed with it this winter are splitting, so apparently mine is past it due date. I honestly have No idea how old it is, I have been buying quarts and just kept topping it off to keep the gallon can filled to prevent air from getting in.
I know I've read on some threads that the quarts/gallons may not be the same now due to VOC requirements.
I like using the spar varnish on maple. Am I better off buying quarts (vs the gallon ?)
