Was looking at some epoxy the other night in the cup as I stirred it and noticed that when the two parts were put into the cup they were nice and clear.
As I stirred, they became cloudy; I assume from the air bubbles introduced.
When I then looked at a fillet and really looked at it, it was full of voids from air bubbles.
Surely those voids contribute to weaker fillets.
Got me to thinking,
Would there be any advantage to putting the mixed epoxy into a vacuum chamber to draw the bubbles out/up before pouring into place as fillets?
I'm not talking anything too scientifically fancy.
As I use a Rival Seal·A·Meal for vaccing purposes, was thinking that if I had one of these - vac canister - I could just use it.
Could be some downsides:

Could be some downsides:
- Need more epoxy for the same size fillet.
- Heavier.
- Harder to sand.[/list=1]
Thoughts?
