Laminating resin is greenish blue in color and is the basic first coat of resin; it is used to adhere the cloth to the blank (this resin will only dry tacky and not sandable!)

Sanding or hot coat resin or filler coat is almost the same thing; it is lam resin with surfacing agent (styrene monomer and paraffin wax) mixed in. Paint it on the laminated surfboard to fill the fiberglass weave and make the board sandable.
Gloss/finish Resin is pink in color and is the final coat of resin. It is similar to sanding resin but is highly filtered and has certain polymers added to help buff up to a brilliant shine. Paint it on the sanded surfboard to give it a shiny finish. It should be polished out to bring out the board&#;s luster.
