This product is useful for molds where clarity is needed to see casting material fill the cavity. This liquid polyurethane rubber can also be used for casting clear amber or color-cast flexible art objects and décor. Poly 74-30 Clear is a pourable rubber, but it can be easily thickened with PolyFiber II Thickener for brush-on application.
