Chaz Gordon I'm just making my first foray into making molds too. If all goes well, I'll have a mold set to churn out Big Block chevys by tomorrow. For the little pieces that need a 2 sided mold, I'm trying out using Polymer clay, which can be baked in the oven at 110º C once the impressions from one side of the parts has been taken (don't bake the parts though) Then I put all the parts back in with a little PVA to hold in place, then pour silicone over the top.

JD I'm watching the mold making process too. Have tried using Blue stuff, but it's pretty hard to get all the details, and like anything, takes practice. Plus that stuff is really hot to work with since you have to boil it.

Christian W I tried blue stuff for the wider wheel houses. That worked not well. The time to use blue stuff is to short to get a good mold of it. So there is no other possibility to build the wheel house extension scratch.
