After a bumper is damaged, the following repair methods can be used:
1. Thermoplastic repair: For plastic bumpers, if cracks or breaks occur, thermoplastic repair technology can be used. This method heats the plastic to a certain temperature to soften it, then fills the cracks or reconnects the broken parts. After cooling, the plastic will harden again and restore its shape and strength.
2. Hot air welding: This is a repair technology suitable for plastic bumpers. It is repaired by using a hot air gun to heat the edge of the plastic and then using a plastic welding rod to fill the damaged area. This method is suitable for cracks or breaks in larger areas.
3. Filler repair: For some small scratches or dents, special fillers can be used to repair them. After the filler dries and hardens, it can be smoothed and then painted to match the body color, so that the repaired part is visually indistinguishable from the original body.
4. Painting: If the main damage to the bumper is scratches or fading, it may only require surface treatment and repainting. This usually involves sanding the damaged area, cleaning, and then applying primer and color paint.
5. Replace the bumper skin: For cases where the surface is damaged but the internal structure is intact, you can consider replacing only the outer skin of the bumper. This method is relatively low-cost, but it may not be easy to find suitable replacement parts for some models.
Which method to choose depends on the type and degree of damage to the bumper and the desired effect after the repair. For complex or severe damage, SHINESELL recommends consulting a professional auto repair technician to ensure the quality and safety of the repair.
