i need info about making moulds...anyone able to help me? i want to cast resin figures,some of them highly detailed..scales from 120mm and bigger..where can i find info?

I use this product for both the molds and the resin cast material. It is called Smooth On. I have been making my gun truck parts with their material for years. They have a great starter kit with all the material needed to get started. They have CD instructions and how to guides to preform all the different types of casting that are done today. These guys are great and easy to talk to.
