INSTRUCTIONS: Apply to a clean dry surface only. For best results apply to a properly prepared surface. This product is designed for hand application only using a microfiber sponge applicator. Mist the applicator (not the surface) with a single spray of Nano Coating . One spray is enough sealant to cover a surface area of 3 to 5 square feet. Apply a very thin coat to the entire surface rub in thoroughly until only a light film remains then wipe off all excess. Allow to dry 8 to 12 hours before getting wet. For additional protection apply SEA-SHIELD Exhaust Guard after the Nano Coating is fully cured.
