A question for you casting guys....

I want to do a 2 part RTV mold and was wondering if anyone ever used Play Doh as the clay base?

I haven't used Play-Doh, but I have used modeling clay. It's also called "plastilina" no 1 and is an oil/parafin based clay that does not harden. It leaves a sort of matte surface on the silicone where it touches. One nice thing is you can melt the modeling clay in the oven (around 200 deg F) and let it cool to produce a flat surface.

I have tried it before but found that it does not conform to the lure to be copied very well.
