What is a Hammercoat Bed Liner?
Hammercoat bed liners are a spray-applied polyurethane coating that creates a molded protective liner. Hammercoat isn't rubber. The chemical composition of Hammercoat makes it much more durable than rubber. It is flexible, rust resistant, chemical resistant, wear resistant and scratch resistant. Unlike rubber, it won't break down due to UV exposure. Because Hammercoat is 100% solids polyurethane, it does not contain any solvents and therefore will not break down over time.

Hammercoat Frequently Asked Questions:
How long do you need my truck to apply a Hammercoat liner?
The entire process takes about 4 hours from start to finish. If the truck is excessively dirty or accessories need to be removed, the process could take longer. You should expect to be without your truck for a day.
How long do I need to wait before I can use my Hammercoat liner?
Hammercoat sets up very quickly and becomes tack-free within one minute. We suggest allowing the liner to cure or 24 hours in a reasonably warm and dry environment before using it.
Will Hammercoat peel?
No. Properly applied, it will stay on virtually forever.
What happens to my drain holes when the liner is sprayed?
Most drain holes are covered over by the liner due to the thickness of Hammercoat. However, in the event you would like drain holes, larger holes can be drilled before the liner is installed. That way the exposed metal edge is sealed by the Hammercoat lining and you have holes available for drainage.
Can it be recoated? What happens if my Hammercoat liner is damaged in a vehicle accident?
No problem. Because Hammercoat is sprayed-on, damaged panels can easily be replaced and the Hammercoat re-sprayed. This creates a seamless repair. Simply take it back to any Hammercoat dealer to re-spray the damaged area.
Why should I go with Hammercoat liner vs. a plastic drop-in liner?
The reasons are too many to list. Plastic drop-in liners vibrate and rub through the paint of your vehicle, exposing bare metal and causing corrosion. Furthermore, plastic drop-in liners warp and crack, and become very slippery when wet. You won't find any of these problems with a Hammercoat liner. Loss of cargo space is also a common problem with drop-ins. Sheets of plywood cannot fit between the wheel wells. Campers cannot be properly loaded either. You won't find these problems with a Hammercoat liner.
