86 OPTIONAL USE OF SEALER PD-1530 Caution: Wear the proper safety protection when sanding, cleaning, mixing and spraying all materials included within this process. Using sealer in the final sanding process has proven to produce flatter paint jobs, less orange peel and better gloss, especially on areas that are difficult to sand and polish, such as door jambs, under hoods, and deck lids. Sealer has a higher level of resin than primers and primer surfacers. This results in a harder surface for the topcoat to be applied over, resulting in a better gloss. PPG sealers also offer recommended shades of gray (G-shades), from G1 white to G7 dark gray, which will help achieve the desired color. 1 Finish sand polyester primer or urethane primer surfacer with P400 grit sandpaper. 2 Select the recommended G1 - G7 shade of gray sealer for the color that will be applied. 3 Clean sanded area with the appropriate PPG cleaner to remove all sanding dust. 4 Apply 2-3 coats of sealer. Allow each coat of sealer to flash to a uniformly dull appearance before applying the next coat. Let sealer dry overnight. 5 Prep for Single Stage: Apply dry guide coat and final sand sealer with a block or sanding pad using wet or dry P400-600 grit sandpaper. Ready for Single Stage, refer to PD-1720. OR Prep for Waterborne basecoat: Apply dry guide coat and finish sand with a block or sanding pad using wet or dry P600-800 grit sandpaper. Ready for Waterborne Basecoat, refer to PD-1710. OR Prep for Solvent Basecoat: Apply dry guide coat and final sand sealer with a block or sanding pad using wet or dry P500-600 grit sandpaper. Ready for Solvent Basecoat, refer to PD-1715. REMEMBER to plan on painting after the final sand. Do not allow sanded sealer to stand for more than 24 hours before applying color. If sanded sealer sits for more than 24 hours, re-clean, sand and clean again before painting.
