i also use those 1or2oz medicine cups

i have a bunch of syringes, but it's awkward w/ extra containers or turning mine upside down or trying to dip into the top of the full resin with the proper syringe without spilling and keeping track of and maybe cleaning syringes over time etc, etc.

so what about 2 eq lengths of clear pvc tubing abt 10-18" long. say 1/4" or thereabouts diam. lay both out beside ruler and mark off say every 1/2". mark one tube for hardener(w/ tape,paint etc).

and use only one syringe. dip just the tube end in the resin and suck up. (might find that the markings are irrelevant). use the markings for proportion. don't suck the resin into the syringe so it never gets dirty.

for dispensing if lucky just squirt out, but probably it'll stick to the sidewalls a bit, so w/ the flex tube just 'milk' it out.
(then just store/hang thetubes somewhere. compact, min mess)
similar to the pipette process that chemists sometimes use.

issues would be volume(tube lenght?) and whether will really dispense(balance of soft/hard for the tube)

but might work
