Glue dispenser?

[gbftats]

Has anyone found a hand pump or other cost effective system to get the 10:1 ratio for 2 part glues? I usually just pour it in a mixing cup, but there is usually waste and I feel like It could be more accurate. I thought about trying pumps for fiberglass resin but im not sure how well that will work since glue is a bit thicker and will probably gum up the nozzle quickly. I buy glue by the gallon, so im obviously not mixing it all at once.

Thanks!

Hand mix is the industry standard.

Reactant ratio isn't too precise. Anywhere from 5 to 15% will work. I use pipettes to measure it, because isocyanate reactant is extremely expensive. About $500 / liter.

I use various paints & fillers for car body repair & weigh to mix which does give a very precise mix - important with the colour basecoats to avoid slight variations in shade/effect.

I usually have a bit left over but if you try & get the total quantity for the job absolutely exact Murphy's Law says that you will have mixed up just a bit too little & it's then a rush to get more mixed & with fast curing products that may be a problem.

We use graduated paint mixing cups and pipettes, i dont see how a dispensing pump would be less wasteful.
