Default Glue for rare earth magnets

I'm looking for info on what kind of glue to use for hatch cover using rare earth magnets. I have previously had a model that I crashed and wanted to save the magnets that held the hatch cover on. That was some tough stuff. Does anyone have any idea what kind of glue the model manufactures us to glue their magnets in?

Any info will be greatly appreciated.

Usually, CA is not recommended for non-porous materials, like metals. I'd try using Goop or clear silicone rubber.

I have used epoxy. Some magnetics are toxic so if you rough them up, don't lick your fingers.

RC-56,or Formula 560, or Canopy Glue or
whatever is its current incarnation. It basically
sticks anything to anything. If you can't find this,
Shoe Goo is pretty good, but may melt some
kinds of foam.

I've used hot glue with good success.

JB Weld works great with other metals. It should work with your magnets.

CA is fine. It only has to be strong enough to not get yanked out by the strength of the magnet or vibrated loose by its weight. If you're worried about it, a dab of epoxy will make a nice little fillet around it which increases the strength of the joint dramatically.

I might as well bring up an old joke that still makes me laugh...
"Sometimes I feel more like a glue collector than a model builder "
