The guy on late nite infomercials advertising Flex Seal...it's like rubber in a can!...They make an airboat out of screen ( like screen door material )and seal it with Flex Seal to make it watertight, and he goes sailing on it through "alligator infested swamp" to prove how good it seals.I didn't get that one lol but anyhow great deal!
