Thanks Cameron. I like the idea of both the vacuum degassing and the use of deairing agent. I will look into finding some of the BYK 525 here in Australia. Building a vacuum degassing chamber might be a good excuse to finally but a venturi valve.
I used West System epoxy with their 206 slow hardener. I used this type mainly because it was the easiest resin to get my hands on that had technical speciations available. There were a few other "no name" epoxy resins around but I couldn't find any product literature on any of them.
The propane torch idea sounds good also! If it can easily remove the bubbles/foam it might be a winner.
