Yes. Using our Tintable Bedliner Kit with quality single part, single stage automotive paint to provide the color is your best choice. This will provide true truck bedliner protection versus simply painting the surface. Using an automotive paint by itself would best be applied only if the bedliner was several years old, but would not supply any more scratch resistance than the original paint did.
Remember… automotive paint applies thin (under 3 mils generally). This does not protect against scratches or abrasion. Our color topcoats and tintable bedliner is designed to apply at approximately 15 mils or more.
