How to Repair a Cracked Car Bumper?

[SanRobert]

The methods to repair a cracked car bumper are: 1. If the paint has chipped, use a touch-up paint pen to cover it, apply paint, and then add a polishing wax; 2. When the bumper is subjected to significant force, it may dent. Heating the dented area with a hairdryer's hot air can help restore it; 3. First, weld the cracked area using plastic welding rods, then smooth and repaint it. After the paint dries, polish it. The principle is that plastic becomes elastic when heated, allowing the deformed plastic to return to its original shape under external force. Bumpers are installed at the front and rear of a car, not only for decorative purposes but also as safety devices that absorb and mitigate external impacts, protecting the vehicle body and ensuring passenger safety.
