Because I've never found a brand of epoxy that comes in toothpaste tubes that
doesn't? The plunger types are even worse though I think I've seen some that
come with a mixing tube that are meant for one time use.

This is my first experience with one that does! In fact, first
experience with anything that comes in a toothpaste-like tube
leaking out AFTER the cap has been firmly screwed on!

Medications, artist paints, other adhesives, toothpaste, etc. have
always "behaved". I've seen folks "squeeze too hard" or "in the middle
of the tube" and get more than they bargained for -- and neglected to clean
off the excess before replacing the cap. But, if there wasn't anything
actively oozing out of the tube when the cap was replaced, I've never
come back to find it having oozed "through" (around) the cap!

The dual-plunger (syringe) behave similarly; if you exert too much
pressure (for the viscosity of the contents), then the stuff oozes
long after you've "stopped pushing" -- as if the stuff is currently
compressed inside the tubes from your pressure and is now looking to
release that pent up energy.

The concrete adhesive that I use is a "two chamber", plunger-driven
sort of storage/dispense mechanism. The "nozzle" through which the
adhesive is dispensed is very long and contains a sort of screw-like
chamber that forces the two-parts to commingle *in* the nozzle before
exiting onto your workpiece. Of course, this makes the nozzle a
single-use item; PLAN AHEad!
