Funny I use Mortite to adjust the mass on passive radiators when I do the initial set up. Seal drivers and it doubles for plumbers putty in a pinch.
Now you know what they forgot on Apollo 13, the Mortite. I know they had duct tape. Maybe if they would have used the Mortite they wouldn’t have had to use the duct tape to get back. I’m pretty sure Mortite will be in Heaven too. LOL
