Wade, I have ordered from both companies and have had great results from both. I use the Mold Max 30 (10:1) for my molds and the Smooth cast 322 (1:1) for my castings. The Mold Max 30 rubber is silicone and holds up well to several castings and the Smooth cast 322 has a pot life ( about 5 minutes, total cure approx 4 hrs) which gives me enough time for pouring several molds at a time. I order the casting products from a supplier named Reynolds Advanced Materials out of Dallas which sells the Smooth On products at the same cost as the manufacturer but they are much closer to me so I can get my orders in about 2 days. Just sharing my experiences.
