So its happened a few times now, and the cost is starting to add up, and im getting frustrated – any advice very much appreciated!
First, 2 different jars (both glass, metal lids, well sealed) of 50/50 spar varnish/mineral spirits blend turned to gel. They were both only a couple weeks old – poured from a can of varnish only 2 months old. Never left with lids off more than a few minutes.
Then the can of spar varnish (pure, never mixed with anything) turned to gel as well. Im talking gel top to bottom – no skin on top, not thicker or thinner at any point, consistent gel all the way thru.
What am i doing wrong? Ive just opened a 1 gallon can of the same spar varnish, REALLY dont want it to go to waste too…. =(
