Make Auto Rubber Trim w/ Silicone Molds | Tutorial

Part 2 In this video, we go through the process of re-creating a hard to find rubber trim gasket for a 1958 BMW Isetta. We go through the process of setting up a silicone mold, casting a flexible urethane, and give many tips and tricks along the way. We will cast BJB's F-130 High Performance Urethane Rubber to produce a part that looks as good as the original! Shop our selection of cast urethane and silicones, or speak with our technical staff to help you pick the right one. We also have a huge selection of castable polyurethanes for making parts in the mold; from soft, flexible gels, tough rubber, on up to rigid plastics! http://www.BJBenterprises.com TC-5041 Silicone: https://bjbmaterials.com/silicones/pl...
