The market is overrun with different mold making materials and products. Every one has an opinion as to what is the best and easiest to use. We have tried a
large majority of the products and have found that for consistent results, easy of use and durability that silicone is by far (In Our Opinion) the top of the line. While it rates as one of the most
expensive, its ability to withstand the rigors of multiple casting, its fast set time, ease of repair, and the availability of many different shore hardiness' is hard to beat. The only type of mold
that I don't recommend silicone for is a one shot mold used to produce only one casting. We have molds that are over 8 years old and still cast as they did when first made, I have had no other mold
material do that well. I can recommend two companies who produce top- notch silicones, even though the companies don't endorse or recommend the mixing of outside components, I have found that
these two silicones and their catalyst can be mixed with no detrimental results.
