How to Repair Plastic Scratches on Car Bumpers?

For minor scratch treatment, first clean the area that needs to be treated, spray water and wipe it with a towel. Apply polishing compound to the area to be treated, and use a polishing machine to grind at low speed, moving back and forth along the direction of the scratch. Move slowly and apply even pressure. During the polishing process, keep the polishing pad and the paint surface at room temperature. If the temperature of the paint surface exceeds 40℃, spray water to cool it down. Stop polishing when the minor scratches are no longer visible. Rinse off the residual polishing compound with water and dry it with a towel. It is best not to wax immediately after polishing.
I often handle plastic scratches on my car's bumper myself, especially minor ones that are easy to fix. First, wash the scratched area with soapy water and dry it thoroughly. Then, apply a specialized scratch repair compound. Use the included soft cloth to buff in circular motions for a few minutes, and finally polish with a clean cloth. If the scratch isn’t deep, this method can restore the plastic to a smooth finish. For deeper scratches, you can lightly sand the surface with fine sandpaper first, then spray some plastic-specific touch-up paint—the results are comparable to professional repairs. I recommend choosing branded repair products to avoid DIY mishaps. Parking farther away from roadside obstacles can help reduce such scrapes, saving money and hassle while protecting your car’s appearance.
