There's also 500 mile-an-hour Duct Tape ;-)

In this case, used as a gap sealer on Unlimited air racers to prevent pressure that may cause the rear canopies to blow off in flight!

When I worked at Northrop in the sixties we had a tape that we used to hold things down on outside of the Apollo recovery module. We called it Mach 1 duct tape because it was supposed to hold up to Mach 1 during re-entry & of course it was OD Green. Some of the stickiest stuff you'll ever find.
