This flexible collodion product is used to paint over modelling wax to create a protective skin on the wax prior to make-up application. Three or four coats of this fast drying compound is usually sufficient to prepare even a soft wax surface for brush or sponge application of make-up. Rubber Mask Grease is ideally suited for the task of covering the sealed wax but you may use whatever make-up you like. Often, a texture can be successfully applied to the wax after the first coat of Flexible Wax Sealer. 1 oz.
