The present invention provides a pre-packaged kit and a method for creating unique multi-toned custom patterns or camouflage on a surface, and in particular the surfaces of a firearm. The multi-toned custom patterns or camouflage are created by separating or peeling off pre-cut stencil/templates from sheet or roll stock adhesive backed masking material and applying the stencil/templates to a surface. The surface is subsequently sprayed with coatings, finishers and sealants. Additional layers of stencil/templates are then added and sprayed with various colors or tones of coatings, finishers and sealants to complete the desired effect on the firearm surface.
