Spray Grain restores the grain pattern that is often lost during the repair process. It is a clear, high-viscosity liquid that is applied in large droplets to simulate the texture of leather or vinyl. It is quick drying and may be force dried for even faster repairs. Touch Up Pigment, Base Coat, or Top Coat is used over Spray Grain to complete the repair. Spray Grain is usually applied with a mouth atomizer but may be applied with an airbrush that is adjusted to spatter rather than spray a smooth coat.
