Introduction
Plastic car bumpers are designed to absorb impact and protect the body of the vehicle. However, even minor collisions can cause holes or cracks in the plastic. If left unrepaired, these holes can allow water and debris into the bumper, leading to rust and further damage. Fortunately, it is relatively easy to fix a hole in a plastic car bumper with the right tools and materials.

2. Sand the Area
Once the area is clean, sand the surface of the bumper around the hole using 80-grit sandpaper. This will create a rough surface that will help the plastic welding rod or filler adhere better.
3. Weld or Fill the Hole
If the hole is small (less than 1/2 inch), you can use a plastic welding iron to melt and fuse a plastic welding rod into the hole. If the hole is larger, you can use a hot air gun and plastic filler to fill it.
- To plastic weld the hole, heat the welding iron and melt the plastic welding rod. Apply the melted plastic to the hole and smooth it out with a plastic welding tool.
- To fill the hole with plastic filler, heat the filler rod with the hot air gun and apply it to the hole. Use a plastic filler tool to smooth out the filler and fill any voids.
4. Sand and Smooth the Repair
Once the hole is filled, allow the repair to cool completely. Then, sand the repaired area with 220-grit sandpaper to smooth out the surface.
5. Apply Auto Body Filler (Optional)
If you want to achieve a professional-looking finish, apply auto body filler to the repaired area. Use a putty knife to spread the filler over the repair and smooth it out. Allow the filler to dry completely and then sand it smooth with 220-grit sandpaper.
6. Prime and Paint (Optional)
To protect the repair and give it a finished look, apply a coat of primer and automotive paint. Allow the primer to dry completely before applying the paint.
