got a question for those of you that have molded bodies using this stuff,how do you shrink it to make a mold from it? i.e if i want to use a hotwheel for a mold for an afx or t- jet ?how do i get it to the correct size? i'd like to give this a shot.

As far as i know, Roger Corrie (VaBchRog) is the only one on the board who has done this... If I understand correctly, the Hydrospan comes with directions that include a formula for how much water to mix in the resin for a given percentage of shrinkage. As the water evaporates, the cast shrinks. Roger had the math all worked out and tested and in practice...
