Herculiner is a high quality and affordable alternative to plastic drop-in liners and professionally-applied spray-on liners, which can cost upwards of $500 to $600. Plastic drop-in liners also require drilling mounting holes into the bed, increasing the chance of the very rust that bed liners are intended to prevent. Herculiner truck bed liner is a ready-to-use, easy application product that beautifies and protects trucks from abuse and the environmental damage. Herculiner truck bed liner is waterproof and resistant to UV rays, chemicals and acids. Please specify a color.

This cannot be shipped by any air services, only ground.

Herculiner Must be applied in a well ventilated area.
The Herculiner smell lingers for up to a week so be prepared to have a ventilated area ready.
Herculiner truck bed liner is nearly impossible to remove from skin. If you get some on you, clean it off immediately with Xylene, then wash the area with soap and water.
It is critical that you do NOT rush the prep phase. The more time you take scuffing the paint, the better the Herculiner truck bed liner will adhere to your truck bed.
When you think you've scuffed the surface enough... you haven't. It takes several passes to get the appropriate "roughness" which causes the Herculiner truck bed liner to adhere properly. The places you did not rough up enough are the places the Herculiner will begin to wear away first.
The instructions state "preparation & application takes about 4 hours". More typically, the prep work is done over the course of a few days -- a little bit at a time. On average, it takes about 4 hours to "rough up" the entire surface which you intend to coat with the Herculiner -- that is AFTER you've spent a considerable amount of time cleaning out the vehicle to the bare bones first. Of course, this process takes longer when applying Herculiner truck bed liner to the interior of Jeeps, Broncos, and such.
It takes about an hour to apply each coat... plus allow for 2 hours of drying time in between coats.
Herculiner has a tendency to fade to grey with prolonged exposure to sunlight (causes UV damage to the Herculiner). To restore the luster to Herculiner, simply clean it with Spic'n Span and rinse throughly. Then you can apply Armor All (surface will become slippery).
Eventually all liners made from polyurethane materials (like Herculiner, Rhino Lining, etc.) will begin to turn a chalky white/gray color. This is a form of fading that can be cured with a special conditioner that brings the black gloss back out.
After the first coat alone, you might question the results, however, you just need the full 2 coats to get the real look and durability of Herculiner truck bed liner.
Herculiner truck bed liner cannot be removed. While you use Xylene while the Herculiner is still wet, if it dries, it's permanent (...which is also a GOOD thing).
For repeated heavy-duty use of the truck bed, an additional coat or two would be recommended.
The ultimate thickness of the Herculiner coating on your truck bed depends on the number of coats you apply. Most are happiest when they go a step farther and apply a 3rd or even 4th coat to the bed of the truck for even greater durability and longevity. At the very least, you might consider applying an extra coat on the tailgate because that is where most things are placed (or dropped) first. If desired, you could go a bit thinner on the sides, since most items don't hit or rest there.
Herculiner is by far the easiest to use and most efficient and cost effective way to cover the bed of your truck.
