I just tried to make my first Silicone Rubber mold, and long story short: IT WONT CURE!!
I don't know if have something to do with the batch (is about 3 years old), the point is that for over two days now, I have 4 Heads submerged in Silicon Rubber that has the consistence of melted Velveeta cheese!!!
Please, can somebody give me a hint on how to help the curing process or in the worst case how to clean up the heads?
For reference I used Alumilite's High Strength 2.
