I too use the 3 oz plastic 'bathroom' cups. Fill one with part A, the other with part B, then mix the two parts together in a tuna fish can. It's enough to glue up any laminated bow I've ever built. For mixing I use a couple of pieces of osage scraps 5/8 x 3/16 x 6" or so. Wipe em off with acetone when I'm done. I've used them forever.
An excellent spatula or squeegy to spread the glue onto the lams and riser can be made with a cut off piece of .040" or .050" fiberglass 8" or so long. It can be cleaned up afterwards with acetone and reused countless times.
I use vynyl gloves as well, same pair beginning to end usually. You'll learn to make less of a mess as you do more of them.
