This is an excellent video that covers creating a clear silicone rubber mold to deal with a complex parting line or irregular shape. When a project requires a complex parting line, it is often easier to pour the entire mold in one process with clear rubber, then cut your parting line. This process also saves at least a day in creating the mold. This process can be used in automotive, mechanical, fine art and film special effects uses.
