[RE-wrenches] J Box adhesive failure.

[Dave Angelini Offgrid Solar]

Agree with All that Alex wrote!

 I will add that most of my clients are extreme rural and remote. I have
been using a sealent that they can get in small town hardware store for 5
years now. It is by Lock-tite and is polyurethane. It takes a day to skin
over. It is water tight as soon as it goes on for a JB. It is made for roof
and flashing and holds up in the sun. Not expensive and is pretty amazing
at the many other uses. It can repair just about any plastic/rubber that is
cracked. It needs to be sealed with a 5" bolt to preserve the tube after it
is open. It will not last more than a week or so without it.
