Master Tips If applying to bare metal, it’s highly recommended to apply Super-Etch Primer first. It is important to choose the proper temperature range lacquer thinner. Accelerated evaporation can actually condense water vapor within primer surfacer and severely reduce primers adhesion and sanding properties. Sealing is recommended if topcoating with a urethane or synthetic enamel topcoat. Allow an extended flash off time after the use of wax & grease removers due to primers porous nature.
