    5 Steps to DENT REPAIR

    Sometimes your car will get a dent that’s too small to justify the expense of a full body shop repair but too big to simply ignore.
    You can cut your repair cost by doing the body work yourself following these 5 simple steps.

    Step 1 - Remove The Dent

    Gain access to the reverse of the body panel by removing items such as interior trims and door panels.
    For more serious dents, first use a Dent Puller to pull out the damaged area.
    Use a Hammer & Dolly to tap the dent out as close as possible to the original panel line.
    Be sure not to tap the dent out higher than the panel line, leaving enough room for Body Filler.

    Step 2 - Surface Preparation

    Before you can fill the dent you need to remove the paint, as Body Filler doesn’t stick well to paint.
  • Use an abrasive pad or 36-40 grit speed file paper to remove all paint from the dent and surrounding area.
  • Clean the area with a Prepwash Wax and Grease Remover.
  • Treat any evident rusted metal with a Rust Converter.

    Step 3 - Apply Filler

    Mix the required amount of body filler with a hardener until a uniform mixture is obtained.
  • Apply Body Filler with an applicator to cover dented area.
  • Be sure to work the Body Filler outside the dent as well as into the crease so there is enough material to feather back once sanding begins
  • Allow to cure for approximately 20-30 minutes.

    Step 4 - Shape & Sand

    Carefully sand back until the filler is level with the surrounding panel.
  • For the best results begin with a course grit speed file paper and work up to a 120 grit sandpaper.
  • You may find that larger dents require several applications of filler or spot putty before a good surface is achieved

    Step 5 - Finishing

    Ensure you clean all surfaces with a wax & grease remover before you begin any painting.
  • Mask surrounding areas with Masking Tape to avoid overspray.
  • Apply a Surface Primer or Primer Putty to fill any sanding marks remaining in the repair.
  • Spray a coat of Etch Primer and sand back using wet and dry sandpaper to remove scratches.
  • Clean the surface again with Prepwash and wipe dry with a clean cloth.
  • Apply 2 to 3 coats of your selected Acrylic Basecoat Colour to the repaired area allowing 10 minutes between coats.
  • Once the basecoat is dried, thoroughly apply Clear Top Coat as required and let it flash dry for 5 minutes before applying additional coats.
  • For the best result it may require a light sand with 2000 grit wet and dry paper and a final polish.
