Put simply, this is a thickened polyester laminating resin. Specifically, this material is used when making fiberglass molds or parts from molds, and is used as the first coating to insure a resin rich coating on the outside of the part being produced. This is a tougher type of resin than our standard polyester resin and will give a durable glossy finish to your parts. Available in black, white or clear (which can be pigmented to suit your needs.) INCLUDES: 1/2 oz MEKP POLYESTER CATALYST
