Apollo 17 Moonbuggy fender repaired with duct tape.
Cernan: "And I hate to say it, but I'm going to have to take some time to try … to get that fender back on. Jack, is the tape under my seat, do you remember?" (He's referring to a roll of ordinary, gray duct tape.)
Cernan: "Okay. I can't say I'm very adept at putting fenders back on. But I sure don't want to start without it. I'm just going to put a couple of pieces of good old-fashioned American gray tape on it...(and) see whether we can't make sure it stays."
In spite of his thick gloves, Cernan managed to unroll and tear off the needed pieces, but moondust foiled his first repair:
Cernan: "…good old-fashioned gray tape doesn't want to stick very well." (At a post flight briefing he explained: "Because there was dust on everything, once you got a piece of tape off the roll, the first thing the tape stuck to was dust; and then it didn't stick to anything else.")
His second attempt succeeded, however. "I am done!" crowed Cernan. "If that fender stays on ... I'd like some sort of mending award." And with that, they were off.
