96 SEALER APPLICATION PROCESS PD-1701 Caution: Wear the proper safety protection when sanding, cleaning, mixing and spraying all materials included within this process. 1 Sealer application is an optional step. If you choose to apply sealer, finish sand with P320-P400 grit. 2 Mask vehicle appropriately. If masking door jambs, etc., that have already been painted, be aware that the first coat of sealer will travel farther into the jamb than the color coats that follow. This will leave an undesired sealer edge. To minimize this effect, mask jambs for color application. Mask a second time, closer to the edge for sealer application. After sealer is applied, remove this masking before applying color and clearcoats. 3 Select the recommended G1 - G7 shade of gray sealer for the color that will be applied. 4 Clean area to be sealed with the appropriate PPG cleaner, and dry with clean towels. The use of a tack cloth is recommended to remove any final dust. 5 Apply sealer. Refer to PD 1530 for specific application instructions. 6 Allow each coat of sealer to flash to a uniformly dull appearance before applying the next coat. 7 Clean spray gun immediately following the application of the final coat of sealer. 8 Allow the sealer to air dry according to the PDS recommendations before applying basecoat.
