I also have some of this. View attachment 183647

That says "interior use" and "water cleanup" on it. Not sure I would use it on anything that might get wet outside. I have started using superglue on some pieces and that seems to work well.

The primary reason I didn't use it was it said interior use only, but I must admit I've never used any kind of glue on a firearm before, so I wasn't sure.

Experiment with the superglue on some scrap pieces if you wish first. Also check woodworking places. There should be some exterior glues available.
