Concrete Mold Making - Other Crafts

It's a web site for a company named Smooth-On. They have some really excellent step-by-steps on how to make molds for 3-D models. Here's my shopping list to make it happen: 2-Gallon Kit “Brush on 50” Polyurethane Rubber for the mold. $98.00 Sealer - will be plain old shellac, which I already have. Release agent “In & Out” (brush or spray on) $31.50 Plasti-paste 1-1/2 gallon (to create the "mother mold" around the inner polyurethane mold) $44.00 All this adds up to around $175 plus shipping. It seems a bit excessive for (1) mold. I know a few of you have done this type of work before. Any advice would be much appreciated. Mahalo! Aaron
