  1. Wash the entire panel and surrounding areas with water and a mild detergent soap; rinse thoroughly and wipe dry.
  2. Clean the entire panel with PPG D837 Acryli-Clean or equivalent.
  3. Prepare all damaged and bare metal areas. Refer to the appropriate section on repair or undercoating in this service manual.
  4. Sand the repair area (primer area 1). Wet sand with 400 grade or finer sandpaper or dry sand with 320 grade or finer sandpaper.
  5. Thoroughly sand the entire panel area with 1200 grade or finer sandpaper.
  6. Clean the entire panel with PPG D846 Multi-Prep Cleaner or equivalent, to remove the sanding residue.
  7. Use an air blow gun to remove all dirt from the cracks and surfaces of the panel.
  8. Tack the entire panel with a clean tack rag.
  9. Mix the base coat color. Refer to the product label instructions.
  10. Apply the first coat of basecoat color over the repaired area only. Use 207 - 275 kPa (30 - 40 psi) of air pressure at the gun. Allow 5 to 10 minutes flash time between each coat of basecoat color.
  11. Apply the second coat of basecoat color over the same area as the first and about 4 to 6 inches beyond where the first coat ended.
  12. Apply the third coat, if needed, over the same area as the second coat and about 4 to 6 inches beyond where the second coat ended. Normally 2 or 3 coats are required to obtain hiding. Do not melt in the dry edge of the basecoat color after finishing the blend; the clearcoat will take care of this.
  13. Allow the final coat of basecoat color to flash for at least 15 minutes, but no longer than 12 hours, before applying the clearcoat.
  14. Mix 2 component clearcoat. Refer to the product label instructions.
  15. Apply 2 or 3 medium wet coats of clear over the entire panel. Use 276 - 344 kPa (40-50 psi) of air pressure at the gun. Allow 5 to 10 minutes flash time between coats.
