It is an honour to meet someone here who has had experience with this! There are very few of us it would seem. Our current method involves a hot water bath for the resin directly after mixing the A & B. The heat pushes all the bubbles to the top and when I pour it into the mold there are zero bubbles. However, once we start dropping little crystals into the mix, small bubbles start to appear again and must be worked out with a tooth pick. The final results are getting better but still not 100% bubble free. I am okay with this I think ;)
Many thanks for the encouraging comment!
