Understanding the Scratch and Gathering Your Supplies

Before diving into the repair, assess the damage. Is it a light surface scratch, a deep gouge, or something in between? Knowing the severity of the scratch will determine the best repair method.

For light scratches, you’ll need items like a microfiber cloth, car wash soap, rubbing compound, and plastic polish. Deeper scratches require more specialized supplies such as plastic filler primer, sandpaper (various grits), and touch-up paint.

How to Repair Light Scratches on a Plastic Car Bumper

Light scratches often respond well to simple cleaning and polishing.

Wash the area: Thoroughly clean the scratched area with car wash soap and water. This removes dirt and grime that can interfere with the repair process.
Apply rubbing compound: Using a microfiber cloth, apply a small amount of rubbing compound to the scratch, working in circular motions.
Buff and polish: After the rubbing compound has dried to a haze, buff it off with a clean microfiber cloth. Follow up with a plastic polish to restore shine.

Repairing Deeper Scratches on Your Car’s Plastic Bumper

Deeper scratches require a more involved approach.

Clean and prep: Just as with light scratches, start by cleaning the area thoroughly. Then, lightly sand the scratched area with fine-grit sandpaper (e.g., 2000-grit) to smooth the edges and create a better surface for the filler primer to adhere to.
Apply filler primer: Apply a thin, even coat of plastic filler primer to the scratch. Allow it to dry completely according to the manufacturer’s instructions.
Sand and smooth: Once dry, sand the primed area with progressively finer grits of sandpaper (e.g., 1500, then 2000) until the surface is smooth and level with the surrounding bumper.
Apply touch-up paint: If necessary, apply touch-up paint to the repaired area, blending it carefully with the surrounding paint. how to repair deep scratches on car plastic bumper
