When 100-mile-an-hour tape won't cut it- 3m offers "Nuclear Grade" duct tape. It seems to be the tape of choice for repairs around the ol' nuclear power plant since it's certified to contain only traces of chlorine, fluoride, bromine and sulfur. Other than that, the stuff offers more strength, cleaner removal and better adhesion than the "Coal Fired Power Plant Grade" tape I get at Home Depot. And it's only $16 a roll. Downside? Not available in green. (Pic from 3M)
