Why do you have to wait for the first pour of silicone to dry before adding additional silicone?
I'm so glad you asked this question! My teacher at school would let it cure first, so I've always done it that way – without questioning it! So I just did some research and in fact you don't have to wait until it's cured. You can immediately mix up another small batch and add it, just like we did the first pour. Just go slowly and keep the point of pour contact away from the base of the model and all will be well!
Thanks for instigating some learning for me too!
