Which Works Best?
Generally, drop-ins are thicker and therefore provide better protection from really heavy cargo. They're also less expensive, easier to install and removable. A spray-on liner, on the other hand, forms a permanent bond with the sheet metal, sealing out corrosion-causing moisture that can be trapped between a drop-in and the bed floor. Spray-ons also give your truck bed a custom look, especially if the liner is color-matched to your truck's paint job.
