Allow each coat to dry before applying additional coats if needed.
Test the nail polish color on a piece of paper, as it may change slightly when dried.
Remember that the effectiveness of these methods may vary based on the severity of the scratches and the type of paint used on your car. Always perform a patch test in an inconspicuous area before applying any products to the scratched surface. If the scratches are deep or extensive, professional help may be required for optimal results.
