The simplest option for you to add bedliner protection if you are looking for a smooth finish is to use our Tintable Bedliner products such as: https://store.sprayliningandcoatings.com/product/tintable-bed-liner-kit/ . This kit consists of 1 gallon A Clear, and ½ gallon of BR. It is mixed at a 2:1 ratio, and you add 1 part (½ gallon total) of your own automotive single part, single stage paint (available at your local automotive finishes supplier) for the color base. We can also provide the automotive color tint, but the cost is generally lower for you to supply locally. Any paint code can be matched relatively well using this product.
This tintable bed liner can usually be applied with an HVLP gun (provided in this kit) depending on the air compressor capacity you have available. The end result is a colored product which is far thicker than can be achieved even with 20 coats of automotive paint, and usually requires only one or two coats.
The alternative is one of our colored truck bed liner kits which are a 2 part process. You first apply the bed liner in a light grey color and get the desired texture depending on the thickness, air pressure control, and tip selection along with the percentage and types of powders you add to your specific mix. You control all these aspects to apply a base coat.
Step 2 involves applying the color coat after the base coat has partially cured. This is similar to painting a vehicle, except that you are applying a very thick bedliner product which is textured to your specific needs. This step is the same as the tintable clear in the first option. The end result in this process is an even thicker coating with more texture than can be achieved with a liquids only product.
