Alumilite Rubber to Rubber Mold Release is brushed on between the first and second pours of silicone when making a two piece mold to ensure the two pours do not bond together. For best results, shake well and apply 2 to 3 coats, allowing each to dry before applying the next. This listing is for 1 ounce of mold release. Due to the size of the bottle, it may feel empty, but 1 ounce of material is included in the container.
