Varnish in jars - the jar won.
Joe in a Cleveland suburb
Last winter I decanted a can of P&L 38 into several jars. The jars have been sitting upside down in a cabinet since.
I've been building a bookcase for my son since last winter - I'm very slow. The shelves are made out of Maple plywood. I wanted to see what the P&L would look like on the plywood. This bookcase is frame and panel, the panels are made of maple and finished with the P&L (I finished them before glue up).
I wanted to put some P&L on a piece of scrap plywood. I tried to open the jar. No luck. It was stuck. Tried everything. I was able to unscrew the lid but couldn't get the flat part off - you know the two piece lids of a mason jar. It seemed to be glued on. The rubber seal and the lid were stuck.
Finally took a screwdriver and started to pry it off. Was having an incredibly hard time. The jar was winning. Finally, in a sudden explosion, the lid popped off, the jar went flying out of my hand and landed on my cabinet saw. The varnish went flying all over as well. Not a drop on the piece of scrap ply though.
It was all over my cabinet saw. The fence. All over my pants and shoes. On the floor and even on one of my dogs that was standing next to me (always under foot this dog). It got on her head, her chest, and her feet.
What a mess. Can't understand why I torture myself with this woodworking stuff.
