While WD-40 is a versatile product for many purposes, it is not recommended for use on car paint. WD-40 is a solvent that can potentially damage the clear coat of your car's paint, causing it to appear dull or faded over time. Additionally, WD-40 is a petroleum-based product, which means it can attract dust and dirt, making your car more prone to grime buildup.
For cleaning and protecting the finish of your car, it is best to use car-specific products designed to be gentle on automotive paint. These products are formulated to remove dirt and grime without damaging the clear coat and often provide a layer of protection to help maintain the shine and longevity of your car's finish.
