Yes, modern cars still benefit from waxing. Waxing helps protect the paint from environmental damage, enhances shine, and makes washing easier by reducing the buildup of dirt and contaminants. While newer paint technologies are more durable, waxing provides an added layer of protection and aesthetic appeal.

modern cars do benefit from waxing, despite advancements in paint technology. Here are some key points to consider:

1. Protection Against Elements: While modern cars often come with a clear coat that protects the paint, waxing adds an extra layer of protection against environmental factors such as UV rays, road salt, and pollutants. This can help prevent damage and maintain the car's appearance over time.

2. Enhancing Shine: Waxing not only protects the paint but also enhances its shine, making the car look newer and well-maintained. This is particularly important for those who want to keep their vehicle looking its best.

3. Frequency of Waxing: If your car is frequently exposed to harsh conditions (like snow, rain, or sun), it's recommended to wax it every three to four months. For cars that are mostly garaged or not exposed to the elements, waxing can be done less frequently.

4. New Cars: Even new cars should be waxed. Some may not have any protective coating applied at the factory, and waxing can help slow down the wear and tear process that begins as soon as the car leaves the dealership.   In summary, while modern cars have protective coatings, regular waxing is still recommended to enhance protection and maintain the vehicle's aesthetic appeal.
