Why the newly sprayed paint appears whiter than the old paint:
1：The color ratio might not be adjusted properly. In this case, it's recommended to redo the paint job or transitionally repaint to make the colors more similar.
2：If the ratio is correct, it's possible that the original paint has yellowed over time. After a while, the newly sprayed white paint will also yellow, matching the original paint.
How to repair a minor scratch on a white car?
If it's just a minor scratch, there's no need for a local repaint. You can visit a car beauty shop and ask the staff to use a polishing machine with fine wax to grind it down, restoring its original look.
Alternatively, you can purchase touch-up paint or other products designed to treat minor scratches. Ensure you buy the touch-up paint that matches your car's color and apply it following the product's instructions.
You can also buy scratch repair wax for car paint. First, clean the scratched area thoroughly. Once the paint is dry, apply the scratch wax. Then use a clean towel to wipe back and forth in straight lines until the paint surface is restored.
If the scratch is deep and can't be fixed directly with touch-up paint or scratch wax, you'll need to use putty to fill in the scratched area. Once the putty is dry, sand it down with sandpaper. Next, spray the touch-up paint onto the scratched area until there's no color difference. Finally, use a cloth to wipe away any excess paint around the scratch.
