I guess I deserved that comment Omar.
I have used silicone from Silicone, Inc and from Make Your Own Molds. MYOM is easy to use.
I don't really get the "bib" that is being described. I'm going to assume there is a negative for the silicone. Silicone captures a lot of little bubbles that need to be removed. A vacuum is the best device for this but not practical. $$$. I use a two pour technique. Mix using a scale according to manufacturer directions. Then long pour that mix into a new clean bucket. Long pour that mix to make your mold. The long pour is a thin strand of liquid silcone that stretches and reduces the air bubbles. Then I use a vibrator. Yes, that kind of vibrator to agitate the mold for several minutes. Remove as many air bubbles. It's pretty good not perfect.
Wear gloves because it can get messy.
Tell me more about the mold negative. Do you want a thin sheet to cut a bib from for the machine?
