Genesis Basics: Protective Layer This step is recommended but not essential. In our last baking step, we'll be applying a thin layer of varnish to protect our painting. Genesis Matte Varnish is a must-have item in your reborning arsenal. It serves several functions: It protects our painted layers from UV and friction, removes any residual shine from the vinyl, and creates a realistic looking skin texture. Using the palette knife, scoop 1 -1 1/2 tablespoons of varnish onto your paint tray. Add enough thinner to make the varnish easy to spread. The thinned varnish should be roughly the consistency of Elmer's glue. Using a clean cosmetic sponge, dip into the varnish and apply to all the vinyl parts with a pouncing motion, leaving some texture. Bake the vinyl parts for 8 minutes at 265 degrees. Remove from the oven and flip the pieces over. Bake for an additional minute. Once set, Genesis Matte Varnish should have a slightly rough texture. If any parts look chalky or feel sticky to the touch, return to the oven and bake at 1 minute intervals until thoroughly set. When varnishing, correct oven temperature is essential. A cool oven will not set the varnish completely, and a hot oven will over heat the vinyl. I strongly recommend using an accurate oven thermometer for all paint setting.
