This video will show you how to correctly prepare for painting any new aftermarket replacement part.

Tools Needed:

Instructions:

  1. Start by roughly sanding the black primer using the 320-grit sandpaper.
  2. When you’re done, use the abrasive pad and sand the fender once again.
  3. Repeat the process for the other side. Make sure you don’t miss a spot.
  4. Watch out for imperfections and dents that could need some fixing prior to applying primer. What you want is a smooth and even surface.
  5. If any areas of the new part are going to be exposed to the road like the inside of a fender, we strongly suggest you spray it with gravel guard to protect it from minor dents and premature rusting.
  6. Wipe off any excess gravel guard and drips with a shop rag and let it dry.
  7. When dry, spray the interior of the fender with 2 fine coats of sealer primer. Let it dry.
  8. Repeat the process and spray the outside with 2 fine coats of sealer primer and let it dry completely according to the manufacturer’s recommendations before moving onto next step.
  9. When the primer is completely dry, sand the fender once again using the 500-grit sandpaper. Watch out not to sand through the primer!
  10. Finish sanding using the abrasive pad one last time.
  11. Repeat the process for the other side.
  12. Use a blow gun to remove dust from the fender and wash it with any good surface cleaner.
  13. Make sure you are in a well-ventilated room and wear the appropriate safety gear from now on.
  14. To remove any dust or sand left, wipe the fender thoroughly inside in out with a tack cloth.
  15. Because you won’t be able to paint it once the fender is mounted on the car, spray paint the interior beforehand. Let it dry.
  16. Apply another coat of paint. Let dry.
  17. When completely dry, wipe the fender once again with a tack cloth.
  18. Apply one good coat of clear coating on the inside of the fender. Let dry.
  19. Install the fender on the vehicle and prepare surrounding areas to receive paint.
  20. That’s it!
