Stop in for a cup of coffee
Think of it like plumbers putty that hardens like a rock. I got it to pit some nutserts into a a old sunfish sailboat and then started using the rest on other stuff. I would not attach a panel with it but works great on hard plastics and a friend of mine has a vw bug that the throttle tube kept coming out of the aluminum shroud and used it and it is still on after a year or so.
