Rear bumpers can become damaged from backing into objects, being rear ended or from objects bumping into them. The rear bumper in a Mazda 6 is made of a thick durable plastic material that absorbs most small dings and dents, but can be gouged or punctured. Fix the rear bumper and make it look as good as new. This can be done in just a few hours using materials from an auto parts store.

- Spray can primer
- 400 grit sandpaper

Use 180-grit sandpaper to sand in and around the area that is damaged. If the bumper is torn, the edges of the tear or puncture can be frayed. Sand these edges until they are smooth.
Use a squeegee to apply a thick layer of flexible body filler over the damage. Make sure the damage cannot be seen and is completely covered by the filler. Let the filler dry for one hour.
Sand the dried filler with 220-grit sandpaper until it is level with the surface of the bumper.
Spray a coat of primer over the area until the filler is completely covered. Let the primer dry for 30 minutes.
Sand the dried primer with 400-grit sandpaper to make it smooth and prepare the surface for paint. Wipe the area with wax and grease remover and a towel to remove any dust, grease from fingerprints or wax contaminants. All of these could show up under the new paint.
Spray a total of three to five coats of paint over the repaired area. Use thin coats to avoid runs. Hold the sprayer 6 to 8 inches from the bumper's surface. Let the paint dry for four hours before touching it.
