let it sit in front of a fan or something, after draining it. eventually, after some hosing and wiping, I imagine it would be clean of gas and fumes.
or take it to a collision shop, and have them paint it black. that would probably scratch easily though.
Hey! maby krylon fusion, that plastic bonding paint looks good and is real hard to scratch.
besides, the gas would not combust underwater, and as long as it's open, I dont think much would happen, maby a couple flames. if you had the cap on, BOOM! :whoa:
