Pretty cool! Those won't rot on the porch anytime soon. I had some junky ones that I drained decades-old "gasoline" from my truck's saddle tanks into and then properly disposed of. I had one left with water-contaminated engine drain oil that I gave to a neighbor who races the Baja 1000. He found a place to dispose of the crud and is using it. Too bad I didn't think of something like this!
