Should a Deformed BMW Front Bumper Be Repaired or Replaced?

[Nicole]

If the front bumper is cracked, the decision to repair or replace it can be based on the extent of the damage. Repair Criteria: If the cracked area is relatively small, it can be welded and repaired. However, if the damage exceeds the repairable standard, replacement is necessary. Bumpers are typically made of flexible and soft plastic, though some are metal. The repair method varies depending on the material. Plastic Bumper: First, use sandpaper along with a grinder to sand the cracked area, removing the paint around the damaged part. Avoid using overly coarse sandpaper; 180-grit sandpaper is sufficient. After sanding thoroughly, clean the sanded area with plastic cleaning fluid to remove dirt and impurities. Cut an appropriately sized stainless steel repair mesh and place it over the crack in the plastic shell. Then, apply filler to level the crack. Once the filler has dried, sand it smooth.
