Bedliners are products that shield the inner-side of a truck bed from damage and can also create a skid-resistant surface allowing cargo to stay in place, depending on circumstances. Spray-in bedliners require specific preparation to allow the coating to adhere correctly to the bed; the better the coating adheres will determine how long it will last.
It’s important to recognize the advantages that Spray-in Bedliners have over their Drop-in counterparts. Drop-in liners are a single or multiple insert system made of rubber or plastic. They are designed to protect the truck bed from damage while hauling sharp or heavy objects. They require drilled holes to be installed and held in place, and do not bond to the truck bed. This allows water and other debris to get under the liner, causing corrosion and scratches that can damage the truck permanently. The drop-in liners do not serve to prevent cargo from shifting or sliding. Over time, they will warp and crack.
Spray-in Bedliners come in varying formulations and process methods such as high or low pressure, aromatic or aliphatic, polyurea or polyurethane, or hybrid and solvent base. Performance greatly relies on the initial surface preparation done on the bed. It is possible to have the color of the bedliner match that of the vehicle, but with time, color fade from ultraviolet radiation is inevitable.
