Loctite has an expiration date. I recently tried to an old bottle of red to take care of an issue with a two-piece axle that should have been a one-piece, and discovered that the loctite wouldn't harden. I ordered fresh bottles from McMaster who have them in stock with recent manufacturing dates, and they ship almost instantly. I order the small bottles and have started replacing them at the expiration date, printed on the bottle.
For DUB bottom brackets -- while I want to like them, I just can't. I've had several DUB bb's come through the shop where the spindle was worn away under the bearing sleeve, 180-degrees apart right to left, from the plastic spacer rubbing on the spindle. In wet/dirty environments (Vermont here) the dirt ends up under the spacer and wears away the spindle material, leading to creaks and (eventually) replacement. My theory is that the deflection of the plastic under momentary pedaling load is followed by an unloaded period, where any moisture (and dirt) get sucked into the very tiny gap between the spindle and spacer as the crank revolves. The next pedal stroke then presses that dirt into the spindle, wearing it away. I had a collection going of worn DUB spindles, but I've been cutting up the spindles for other purposes in the shop. (custom press spacers in pivot links mostly).
The exception to the wear has been CaneCreek Hellbender bottom brackets, which replace the plastic spacer with 29mm ID bearings. These - so far - seem to avoid the spindle wear issue. There might be others that avoid the issue, but so far I've only dealt with the CC.
I suppose they're better than GXP, maybe?
That extraction cap falls out all the time though. It's a bit annoying that the cap/washer don't seem to be available without the bolt too. There's some caps available on Amazon from some knockoff company, but I can't install them at my shop in good conscience. They might be 6061 Aluminum, they might be melted down PBR cans - just not worth the risk.
