[Car Knowledge] What are the main differences between PPF vs coating?

PPF (Paint Protection Film) and coating are two common methods of protecting car paint, but they have obvious differences in materials, functions, durability and applicable scenarios. The following are the main differences between the two:

1. Material and form

   • PPF is a transparent film, usually made of polyurethane or other high-strength materials, which is elastic and impact-resistant.
   • Coating is a liquid material, usually composed of chemicals such as silicates, ceramics, silanes or silicides, which is applied to the surface of the car paint to form a solidified protective layer.

2. Protection performance

   • The main function of PPF is physical protection. It can effectively resist external damage such as stone splashes, scratches, minor collisions, and even has a certain self-repair ability (the self-repair function depends on the material).
   • The coating provides chemical protection, mainly enhancing the paint's resistance to oxidation, UV rays and acid rain corrosion, while improving the paint's gloss and hydrophobicity.

3. Appearance

   • PPF is usually completely transparent and does not change the original color of the car's paint, but some special types of PPF (such as matte film or color-changing film) can change the appearance of the vehicle.
   • Coating will make the paint appear shinier and enhance the visual aesthetic of the vehicle, but it will not change the color or texture of the paint.

4. Durability and maintenance

   • The service life of PPF is generally 5 to 10 years, and it has high durability, but it requires regular cleaning and maintenance to prevent aging or edge peeling of the membrane surface.
   • The effect of coating can usually last from 6 months to 2 years, depending on the quality of the product and maintenance. Regular re-coating is required to maintain the effect.

5. Installation difficulty and cost

   • The installation process of PPF is relatively complicated and requires professional technicians to cut and fit, and the installation cost is relatively high.
   • The coating construction is relatively simple, and some car owners can even do it themselves, but the price of high-end coating products is not low.

6. Applicable scenarios

   • PPF is suitable for car owners who want strong physical protection, especially those who often drive on highways or in environments prone to flying stone damage.
   • The coating is more suitable for car owners who pay attention to the glossiness of the vehicle's appearance and long-term anti-oxidation protection, and is suitable for daily use or parking in a good environment.

7. Repair and Replacement

   • If PPF is damaged, it can be replaced locally, but the construction process needs to be cautious to avoid affecting the surrounding membrane layer.
   • Once the coating is worn or fails, it can simply be re-coated, but the damaged car paint cannot be repaired.

In summary, PPF and coating each have their own advantages and limitations, and the choice depends on the needs and budget of the car owner. If you are looking for comprehensive physical protection, PPF is the best choice, while if you are mainly concerned about the gloss and chemical protection of the car paint, coating is a more appropriate choice.
