Fixing a scratched car bumper depends entirely on the depth of the scratch. For light, superficial clear coat scratches that don't catch your fingernail, a DIY repair with a polishing compound is often successful. Deeper scratches that expose the colored base coat or the black plastic primer require touch-up paint. If the scratch has gouged the plastic itself, professional repair or replacement might be the most cost-effective long-term solution. The first step is a thorough assessment. Wash and dry the bumper, then run your fingernail across the scratch. If it doesn't catch, the scratch is likely only in the clear coat. For these, a scratch removal compound and a microfiber cloth can often buff the scratch away by leveling the surrounding clear coat. For scratches that expose color, you'll need an OEM (Original Equipment Manufacturer) touch-up paint pen. This involves carefully cleaning the area, applying the paint in thin layers, allowing it to dry, and then leveling it with a clear coat applicator and polish. | Scratch Depth | Visibility | DIY Repair Difficulty | Estimated DIY Cost | Professional Repair Cost (Avg.) | | :--- | :--- | :--- | :--- | :--- | | Clear Coat Only | Light, shiny | Easy | $20 - $50 (compound) | $150 - $300 | | Base Coat (Color) | Obvious color | Moderate | $30 - $80 (paint pen kit) | $300 - $600 | | Primer/Plastic | White/black gouge | Difficult | $100+ (filler, paint) | $500 - $1,000+ | | Cracked/Dented | Structural damage | Not Recommended | - | $800 - $2,000+ | For deep plastic gouges, a plastic repair epoxy is needed to fill the gap before painting, which significantly increases complexity. The decision to go pro often comes down to the value of your car and your tolerance for a less-than-perfect finish. A professional will use a spray gun for a seamless blend, which is hard to replicate with a brush.
