Hey Jim
Been shopping for HS fuel around town the last few days and all I can find here is rather expensive 70% that has a bunch of different additives like Thieves' Oil (whatever that is) and Aloe or some unpronounceable 47 letter word that looks like trouble, and who knows what it might turn into if burned.
On the other hand, looking online I have found what looks to be a rather generic 75% HS that is also recommended for wiping down counters, tables, bars and the like in food service establishments and all that it has other than the 75% ethanol is glycerin and H2O. It ships free in a gallon jug with a pump dispenser top for a bit over $20, so I guess I'll get a bottle of that and see how it goes. Wish I could get a smaller size just to try out, but at that price it doesn't seem too bad a deal.
