What does "dual layer" mean?
We like to describe the practice of using a base material that is the same color as the painted top coat as having a "dual layer" finish. It means the automotive grade plastic we used has black pigment impregnated within the plastic itself. In other words, we took a black part and then painted it black. We prefer to use this technique in the high-impact zones of the vehicle (typically the front end).
The advantage is that any damage that may occur will be less noticeable when the part has dual layers of black.
Take a high-speed rock chip for example. The only real protection against this kind of damage is a paint protection film (also known as a clear bra). The fact of the matter is, if you throw a rock at any painted surface there is going to be damage. Our goal is to make it less noticeable.
