What if you're using a thixotropic resin ?
I've got one cold cure formulation I use that would have you sitting there all day trying to pull it into the syringe.

I use Epiglass resin and I just keep a damp mineral spirit-soaked piece of rag to wrap around the nozzle on the hardener when I'm done. The resin pump doesn't seem to plug up at all.
I just heat the epoxy and hardener up with a small electric heater with a fan and fill 3 "A",
and 3 "B" syringes at one time. I pull out the plunger and pour it in from the top. Replace the plunger, remove any air bubbles, and then push out any excess resin back into the can until the plunger lines up with a line on the syringe. Takes all of 2 minutes.

Do not measure by weight unless you know the correct ratio.
I measured by weight for a board I made I gave it 2parts resin one part hardener, never cured right always has a smell to it and its soft and fiberglass peels off easy. Turns out it takes a lot more hardener to get the same weight a resin so you get more hardener in the mix.

Mixing up a batch as small as 6cc[1/5 ounce] is even possible. Find yourself a nurse or nurses aide that you may know and ask them to get you 2 of them. Complete accuracy!
