SEM High Build Primer works great for preparing patterns for molding. We feel it's one of the best "Rattle Can" high-fill primers on the market, which is why we sell it! Fills and sands quickly for rapid turnaround (really, it dries FAST). Has shown to work well with Platinum Silicone without inhibition (given sufficient dry time). If you are frustrated with the big-box store primers, give SEM a try in your shop!
