  5. Fine sand with P400 dry sandpaper. Subsequently clean and mask.
  6. Thinly apply 2K Epoxy Primer Filler, then 3 spray processes with forced interim drying.
  7. After full hardening with P800, prebuff with wet emery paper. Fine sand with P1200.
  8. Roughen inner edge zone with grey ultra-fine abrasive pad, outer edge zone with sponge and Schleiffix.
  9. Dry and clean area
  10. Apply a thin spray of 1K water-borne paint to a pre-warmed area (25-30°C) and continue with the normal painting process.
  11. When using barely opaque colour tones, after a corresponding flash time (matt stripped) it might be necessary to apply additional paint processes.
  12. Important: after each painting process, completely flash off the paint.
  13. Paint 2K Rapid Clear Coat in 2 complete paint processes with interim flash off time.
  14. Paint blender thinner / clear coat in light painting steps in all transition zones.
  15. If necessary, polish the transition zones after full hardening.
