Air bubbles!
Posted in: Tech Help, Tips, Tricks, & Techniques
I feel your pain. I hand paintbrush each mold (several coats each) to avoid it, but it's extremely time consuming. You can build a shaker/vibrating table that may help, as well. At school, we'd rap the mold against the table a few times to try and dislodge bubbles. I personally prefer the time consuming method as it allows me to really control the thickness of the walls, but that's just me and I'd certainly change my method if I were working on a commercial scale.

I picked up one from ebay for $10 or $15, IIRC.
