My Daddy always wanted to make fuel-grade shine, cause he HATED paying for gasoline. Us hill-billies and red-necks HATE to pay for ANYTHING that we could make ourselves. Once, he made some shine that ran an old push mower, and of course we just had to taste it. DAMN, that stuff was HOT, kinda like PGA! It burned your eyes, nose, and ALL the way down! One sip was ALL you wanted!
