Is Spray-on Truck Bed Liner Waterproof? Know what is available. I found this a common question with all truck owners who often carry watercraft, boats or kayaks in the back of the truck. I did some research on Truck Bed Liner Waterproof to get the answer.

Is the bed liner spray waterproof and rust proof?

Most of the popular bed liners that are available for the truck beds are waterproof and also rust proof. How long they will last depends on the quality of truck bed liner you apply.

There are many types of bed liners and you can even make one at your home, but if you need a permanent solution and don’t want to bother about your truck bed, the spray-on liner is the best option. Other than making your truck bed waterproof it provides tons of other benefits, but don’t expect it to solve all your bed lining problems unless you apply the right type of bed liner from a reliable manufacturer. Spray-on bed liners are not simple to apply, because it needs some initial prep work and has to be applied by a professional. So, you can’t apply the spray-on liner at your home. However, if you need only waterproofing, there are other simple options available.

Waterproofing Your Truck Bed With Spray-on Bed Liner

Professional:

Spray-on bed liners are essentially a painted coating which has to be applied in a paint shop using a spray gun. Since it is a coating, your truck bed has to be properly prepared to apply the spay. The truck bed has to be stipped down to the primer or base metal using a sander, then it has to be properly cleaned.

Sometimes a chemical cleaner is also used along with the grinding process. Then the liner is applied by trained installers in the shop. They make sure it is not overspray on the back of your truck’s cab, or on the fender. There has to be ample separation between your vehicle and other vehicles; in-fact your truck bed should be sprayed on in an actual spray booth with a separate ventilation system.

DIY:

You can also spray-on the truck bed at the convenience of your home using DIY spray-on and roll-on liners. For that also you have to prep the bed. Start by washing the bed with car wash soap and allow it to fully dry. Scuff the surface with 36 grit sandpaper. Then wipe off all the sanding debris and dust. You could also coat the bed with the adhesion promoter or primer as provided by the manufacturer.

The type of coating that is applied depends on the manufacturer you choose. Most coatings are polyurethane, which hardens when exposed to the atmosphere. There are other types of coatings too such as aromatic and aliphatic, among which the aliphatic variant are expensive because they don’t fade as fast as other options.

The spray-on bed liner creates an airtight seal that doesn’t allow water, dirt, sand or other loose material to make contact with the truck bed. Unlike drop-in liners, it is far most efficient but is also expensive. It can cost you as much as $1000, depending on the type of bed liner you install.

Having said that these waterproof bed liners also offer various types of protection and are available with a lot of other features that could be used to improve the durability and year-long performance as listed below.

Some Cons of Spray-on Bed Liner

  1. They are not removable. You can’t take out your spray-on bed liner out of your old truck and drop it into your new truck.
  2. High-quality bed liners are expensive. Many opt to apply a low-cost coating and re-do it later if needed, hence they don’t worry about the warranty either.
  3. It provides no protection against dents and dings, unlike the drop-in bed liner.
  4. You can’t apply it by yourself. The installers must be trained who are careful and give attention to detail. However, there are DIY roll-on bed liners, but they are prone to damages.

Does It Fade?

As discussed earlier, the aromatic coatings fade whereas aliphatic coatings do not. Most spray-on bed liners are aromatic, which is why they are sensitive to UV light from the sun which makes them fade away in time. Whereas aliphatic coatings are not sensitive to UV light and are more color stable.

There are a few ways you can prevent the fading. You can apply products such as Rhino Shine on the faded liner to bring back its shine. You can also choose to have a UV top coat applied at the time of spraying on the bed liner. We advise you to check your UV coating every three years to make sure it hasn’t scratched.

If you are looking for a more permanent option, you could apply an aliphatic based product; it lasts longer and fades gradually. Another option is to simply take better care by cleaning your bed weekly using products that don’t contain any oil or harsh ingredients.

You also have to keep in mind that it’s permanent and you can’t just peel it off like other plastic dip coatings.

Can I Use This for Undercoating?

If you don’t mind the expense, it’s a great option to undercoat your truck chassis. It provides protection from snow and salt, protects from rock damage, chassis can be cleaned easily, contaminants such as grease and dirt won’t stick to the bed liner.

However, like the usual truck bed, it requires some prep work. First of the undercarriage should be clean and brushed off to make it rough, so it is better if your spray bed liner on a new truck. If you have an older vehicle and need rust repairs, it is the right time to do it.

Is the Texture Really Coarse or Can It be Made into the Texture You Want?

Bed liner texture can be both fine and coarse. It can be adjusted from the panel and air pressure. Lower air pressure provides a greater droplet to make the texture coarser.

What are the Other Types of Truck Bed Liners?

Truck bed liners are typically four types: spray-on, drop-in, bed rug, and bed mat.

  • Most common bed liners are drop-ins; it’s made of plastic and is molded to fit securely on the inside of the truck’s bed.

  • Bed rugs are moderately priced and are more convenient. It lays flat on the bed, or customers can pay more to have the rug stretch up to the sides and onto the tailgate. Bed rugs require no drilling and are molded tightly so nothing gets underneath. It typically costs under $550.
