Repair Small Scale Scratch and Dent with Bondo

crash courses in automotive | Posted: 4/6/2022

Accidents happen, and sometimes a scuff, scratch, or small dent can mess up the lines of your sweet ride. Today we’re going to look at how you can use Bondo to fix small-scale vehicle damage without breaking the bank!

The Bondo brand offers a complete line of fillers, putties, and glazes for many applications, including automotive, household, marine, hobby, and more! The secret to a fast, strong, and permanent repair lies in the two-part technology—a reaction occurs when the filler and hardener are mixed together, allowing the product to chemically bond to the surface you are repairing. Whether you’re fixing a small dent in your car door or building that awesome replica battle helmet, Bondo’s got the product to make it happen.

Bondo Body Repair Kit

Bondo Body Repair Products

Let’s start by taking a look at the original Bondo Body Filler. Here at, we carry this product in either a 397g, 794g, 3.18kg can, or, in a complete body repair kit. The repair kit comes with filler, hardener, spreader, and a self-adhesive metal patch. Before you start to work with Bondo, be sure you’re wearing the proper safety gear—safety glassesgloves, and masks are a must!

Did you know, the original Bondo formula was even used to patch a pothole during the 2010 Daytona 500 — keeping the race, and the cars, on track!

How to Use Bondo for Dent Repairs

  1. First, you need to clean the repair area with soap and water and allow the panel to dry.
  2. Use a residue remover, such as a general-purpose adhesive cleaner, or rubbing alcohol to remove any wax, dirt, or oils.
  3. Sand the surface with sandpaper until you get to the bare metal and then re-clean it.
  4. Take the closed tube of cream hardener and squeeze it between your fingers for about 30 seconds. This will ensure that the hardener is well-mixed and ready to go.
  5. Next, place the amount of filler you need on a clean, flat, non-absorbent mixing surface.
  6. Add a stripe of cream hardener across the middle of the filler and start mixing. Whatever you do, do not overuse the hardener! With more hardener means it will harden faster, which will make application difficult.
  7. You’ll know it’s mixed well enough when the filler and hardener become one even color.
  8. Now that we’ve added the hardener, the filler will start to firm up within 3 to 5 minutes, so you’ve got to work fast!
  9. Apply a thin layer of filler with a spreader, making sure to apply firm pressure with each movement.
  10. Apply additional filler in layers, building up the damaged area slightly higher than the surrounding surface. The filler should never be more than 1/8” thick!
  11. Allow the filler to cure for 20 minutes.
  12. After that, you can start sanding to get the proper contours for the damaged area.
  13. Use a body file on the filler to get some of the roughest edges out of the way and then sand.
  14. If more filler is needed, re-mix from scratch—never return mixed filler to the original can or try to mix the new filler with old.
  15. Make sure you wait at least 45 minutes before applying primer and paint.
