Has anyone found a way to preserve POR-15, after opening it? Options

I buy my POR-15 in quarts, but still never use nearly that much at a time. I tried to seal it in a plastic soda bottle, but it kept pressurizing it and I had to vent it every once in a while (exploding soda bottles are messy, but exploding soda bottles full of POR-15 are messy beyond all comprehension). Eventually it solidified, and I had to toss it.

An unopened can will last for years.. has anyone found a way to preserve that life after opening?

I poured the rest of mine into a large pickle jar. Put plastic wrap over the jar and tighten the lid over the plastic. If you want to use it later and can't get the lid off the jar, poke a hole in the lid and pour it out into something else, like another pickle jar. It doesn't matter if it is a can or a jar, you just have make certain that it is sealed well. I guess no one needs to be cautioned not to get any on ya huh?
