Fstbttms,
EDITED BY CD If you can't figure out how to pour gas onto your driveway with out it running into the gutter or the street your just an idiot. I don't think anyone intelligent enough to sail is so stupid as to be unable to pour out some gas on a hard surface with out trouble. Gas is photovolic. For the uniformed, photovolic fluid are so called because they breakdown in sunlight. Evaporating gas from a container is a good way to spill it, or to forget it and have it flooded with water in the next storm. A gallon of gas in a
paint can would take days if not weeks to evaporate. When spread out on a flat surface like a concrete slab, it can evaporate in a few hours, the remaining residue will break down in a few days. If it rains the next day, the water will slick and run off with out taking much petroleum with it. This is not the way to dispose of twenty gallons but if you have one or two gallon to get rid of, it's a safe way to dispose of it.
