Homebrew PCBs

Basically, the silicon mold is by Alumlite/Dow Corning. You see, 
Alumlite purchases the Dow Corning MS III RTV Rubber compound and 
then repackages it into consumer-friendly quanities. Here is there 
website: http://www.alumilite.com/. 

As for the liquid plastic itself, I am using a liquid resin compound 
from TAP Plastic called, "Fast Casting Liquid Resin". Their site is 
here: 

You can purchase the items from the appropriate websites or you can 
purchase the liquid plastic from your local TAP Plastic store and the 
RTV Compound may(may) be purchased from a hobby shop. Also note that 
Alumilite sells a liquid plastic compound but the cost is much more 
then TAP Plastic's.
