The base coat is applied to cars primarily to protect the underlying layers and provide a surface for the clear coat, resulting in enhanced shine and durability.
Here's a more detailed explanation:
-
Protection from the Elements: The base coat acts as a barrier protecting the primer and the car's frame from environmental factors such as UV rays, moisture, and road debris. This helps prevent rust and corrosion.
-
Provides a Foundation for Clear Coat: The base coat is formulated to create a smooth and even surface, which is essential for the proper adhesion and appearance of the clear coat.
-
Enhanced Appearance: When used in conjunction with a clear coat, the base coat provides a durable and glossy finish, improving the overall aesthetic appeal of the vehicle.
-
Improved Durability: A quality base coat extends the life of the paint job by preventing chipping, fading, and other forms of damage.
