Our premium refinish products are paired with the smooth spraying preval power unit to provide the best finish possible. Each spray unit requires less than 2oz of eco-friendly propellant to spray up to 16 oz of paint. Our custom mixed single stage colors come in a separate solvent proof bottle which connects directly to the preval power unit. Preval s proprietary power unit provides superior paint atomization and gives the smoothest aerosol finish possible. As always all of our products are Made in the USA!
