Yeah but it's funny it didn't turn white until I mixed it. It's old stuff and the resin was crystallized then I left it in hot water to make it clear again. Did water get through the polypropylene bottle? Will try to heat it with dry air and see what happens. I'll be happy if it hardens up so I can get the mold apart.
I don't think the water will prevent it from hardening. It could be a little crumbly in some places depending on how much water is actually trapped in the stuff.
Yes I would guess that there is a very small leak in one of the bottles that allowed some water intrusion into one of the components.
