Nobody wants a damaged truck bed. The problem is that using your truck for its intended purpose may ruin the bed unless you're careful. A load that scratches through the paint and exposes the metal underneath will let rust set in, which quickly destroys the bed.
For years, truck owners have always tried to fight back against bed damage, generally resorting to one of three options: plastic liners, spray-on liners, and bed carpets.
Most common are standard plastic bed liners. Most of these are one-piece designs which slide into the truck bed and then mount onto the truck to hold them in place. They're the most affordable option, but that doesn't mean they're the best choice for you. Why? For example, you may find water collecting under your bed liner, which results in damage. To make matters worse, plastic liners tend to be fairly slick. This can cause problems when you haul cargo, or even when you're walking in the bed.
Bed carpets offer a balance between plastic drop-in liners and spray-on types. These are made from marine-grade polypropylene, which doesn't retain water. Unlike spray-on liners, these don't require professional installation -- you simply roll them out over the bed of your truck. However, bed carpets do not protect every part of your truck bed, and they must be custom-cut to fit your truck.
Spray-on liners tend to be a better solution than plastic drop-in types. A spray-on liner adheres to the bed and the inner sides of the truck bed, giving you better protection than a drop-in plastic liner. They help protect the metal surface from rust and corrosion as they seal tight onto the surface. Line-X of Central Ohio in Columbus offers spray-on liners for better durability and enhanced protection from those elements. Spray-on liners are a more affordable solution as they outweigh any costs, preventing future damage repairs. They will also last longer and provide better performance.
Spray-on liners should always be installed by a professional truck bed liner installer.
