Vent holes in mold to let air escape

Album Info:
Here is an example of several vent holes that were put into the taillight silicone mold to let air escape. This is actally a piece of particle board that was placed on top of the mold (and another piece was placed under) to give it some support in the curing steps. But we drilled/punched holes in both to let the air escape. Otherwise, you'll end up with a big hole in your part where trapped air was located during the curing steps.
