I've had fairly good luck finding squeeze bottles of gelled alcohol fuel. It works pretty well for priming. If you cant find gelled alcohol, Stern can be diluted with alcohol to make it flowable. Regular Sterno is made with methanol, but there is a green Sterno that is made with Ethanol. I scrape some green Sterno into an empty paint can and add denatured alcohol to dilute the Sterno. Put the lid on and let it sit a while. Once it gets fluid enough, I pour some into a plastic squeeze bottle.
