That reminds me of a story....
Many moons ago, my ex (who was working as a pipefitter at the time) was on an oil rig off Alaska. Someone had managed to smuggle a blunt aboard, and a bunch of guys, including him, scooted off to a secluded part of the rig to share it. Not sure if they missed the memo to smoke off the leeward side, but someone caught a whiff and the next thing you know, a helicopter lands with a drug dog. The entire crew were hauled up on deck for mouth swabs while the dog went through the bunkrooms.
Now, The Yeag was (and I assume still is) a quick thinking kinda guy, and the moment he saw that dog hit the decking, he grabbed the closest thing he could find to mask the test. It was a can of WD40. So, with delightfully fresh grease breath, he got swabbed and passed. Bunch of guys were summarily fired and flown off the rig on the helicopter.
I do not recommend this method!
It is, however, further proof that, in a pinch, nearly everything can be fixed with duct tape and/or wd40.
