Step-by-Step Guide: How to Repair Scratches on Plastic Car Bumper

Follow these steps for a successful DIY scratch repair:

Clean the Area: Thoroughly wash the bumper with car wash soap and water. Rinse well and allow it to dry completely.
Sand the Scratch: Using 200-grit sandpaper, gently sand the scratch and the area around it. The goal is to create a smooth, even surface. Gradually increase the sandpaper grit (400, 600, 800) to further smooth the area.
Mask Off the Area: Use masking tape and plastic sheeting to protect the surrounding paintwork.
Prime the Area: If the scratch is deep or you’ve sanded down to the bare plastic, apply a thin coat of primer specifically designed for plastic. Allow it to dry completely.
Apply Touch-Up Paint: Shake the touch-up paint well and carefully apply thin coats to the scratched area, allowing each coat to dry before applying the next.
Apply Clear Coat: Once the touch-up paint is dry, apply a few thin layers of clear coat, allowing each layer to dry completely. This will protect the paint and provide a glossy finish.
Wet Sand and Polish: After the clear coat has cured (typically 24-48 hours), use a rubbing compound with a damp microfiber cloth to smooth out any imperfections. Follow with a polishing compound to restore the shine.

Tips for a Professional-Looking Finish

Work in a well-ventilated area.
Apply thin, even coats of paint and clear coat.
Be patient and allow each layer to dry thoroughly.
