Bubbles- steel epoxy dies., Bubbles- Steel epoxy dies

I have found it difficult to get consistent results using "Devcon Steel Epoxy". I also found the product to be too expensive along with the bubbles created.
I have started to use iron powder mixed with "Devcon Two Ton Epoxy" and find that the bubbles persist. I've tried using a vibrator (vibratory polisher), on the epoxy separately and mixed with the iron powder. I've also tried adding 5% acetone as advised by Devcon with poor results. The opportunity to do anything is severly limited by the fast cure rate of the mix. Because of the extremely thick consistincy and the fast cure rate I cannot imagine the vacum machine being effective.

I would apprectiate any suggestions on bubble elimination.
