So I guess that means nobody has found a viable, cost-effective way to store small amounts of vulcanizing glue? I'd be interested in buying the can of Rema and a 100pk of patches, if I knew of some way to package "single-serving" amounts for my saddle bag.

Travel-size toothpaste tube, rinsed clean?
Dollop in a snack-size ziploc bag, squeeze the air out, seal, fold up, keep safe inside plastic patch-kit box?
Smaller ziploc bags, like for packaging individual screws or tiny parts or selling drugs?
Glass vial for crack, apply by dipping in a qtip or bamboo skewer or stick?
Tiny plastic bottle/jar with bubbles in it, lid has bubble-blowing wand (available cheap in bulk for weddings)?
