Hi, How can I avoid bubbles in the castings when using Xencast (currently general purpose)? The mould is dry but there are always bubbles present, often on the surface ruining the castings.
Many Thanks

Just to check, is this Xencast P2 or P6?

Rich, 

It is P2 and otherwise perfect for the application. I don't actually mind which one as long as it does not have bubbles in it! 

Is there normally bubbles present in the P2 or is it a defect when bubbles appear? I expect it should be possible to get Bubble free castings, I just don't know how to eliminate them.
