This amazing product will set up like plaster but not as quickly. When set it is easily cut or scraped into shape. When completely dry (overnight) you can cut, saw, or rasp it. Does not break or shatter like plaster, and when dry, it is much lighter in weight than plaster. It will not damage or dry rot skins. Good for building up or modeling anywhere or anything. Good for making bodies for small fish. Can be used for making large fish bodies by using a wood or excelsior core. Apply a layer over the excelsior core and place inside the fish skin. Shape fish while plastolite is soft. When set, remove and dry plastolite body before mounting fish.
