A couple of things: Does the cap break if you try to remove it with hot air? If not, than you are breaking the caps do to mechanical stress. We have had similar issues. I don't think your board is suffering from mechanical stress from depaneling o

We don't have the equipment to check specific gravity, we just assume what's on the bottle is correct and we've never had a problem. The stone sits in an open chamber, so there really isn't any pressure to check. When we vary the air flow, the foam
