To spray glossy matte lacquer, start by preparing the surface by sanding it to remove any imperfections and then cleaning it thoroughly. Next, apply a primer to the surface and let it dry completely. Then, use a spray gun to apply the glossy matte lacquer in thin, even coats, holding the gun about 6-8 inches away from the surface. Allow each coat to dry before applying the next one, and make sure to follow the manufacturer's instructions for drying times and application techniques. Finally, sand the surface lightly with fine-grit sandpaper between coats to ensure a smooth finish. **
