having issues with bubbles.
Making automotive Lenses, 2 part Molds are vented, use pressure pot, even use degassing chamber. But still end up with bubbles.
Any thoughts ?

Are you warming up the molds? Are you working in a warm environment? Are you pouring slowly and from a high height? Are you mixing long enough? Were the molds themselves degassed? Has the resin been contaminated with moisture? Walk us through your process and we'll see if we can figure it out. Bubbles are normally a moisture problem but sometimes other things can happen to produce them.
