This kit is designed to allow you to do the color matching. The process is to first apply the bedliner or protective coating mixing 2 components of liquid and a variable mix of powdered components in a light grey color. This allows the build on vertical surfaces and to establish the texture you like.
The color match is done by adding automotive paint which you would purchase from your local auto paint supply to the 2 part clear bedliner provided in the kit.
This allows you to control the exact finished product. For this kit, you would purchase 1 pint of paint locally.
