When mixing up common West Systems epoxy at work (one even dose via pump bottles) I always get tiny little bubbles appearing in the mix container (a small tunafish tin). These bubbles then obviously end up in the work piece, and while some amalgamate into bigger surface bubbles that can be popped before curing, there always seems to be a little bit of "fizz" left behind in the cavity (ie: small holes like bird's eyes and/or bigger "tears").
Am I expecting too much wanting a completely solid mix, or am I doing something wrong?
I've tried changing the way I mix with smaller/bigger stirring sticks and by stirring less vigorously but I can't for the life of me stop "introducing" these little bubbles at the mixing stage.
The teeny bubbles don't stand out *too* much when fully cured, and I know that customers haven't seen them, but I know the blighters are there and it's messing with my OCD :q
