This post will compare bedliner options, with cross section illustrations, and give you the facts on why DualLiner is the best bed liner on the market. DualLiner also offers the most protection for your truck. Obviously you want your bedliner to keep your cargo in place, prevent scratches to your truck, and of course you want it to look good. Many truck owners buy a bedliner for maximum protection against shock and impact. Here, with cross sections, you’ll see which bedliner offers all of these benefits.
DualLiner Truck Bedliners Revealed!
DualLiner bedliners are a multi-piece liner made of different materials. Each bedliner part is made from the best material for the function of the part. The 5 pieces all connect and fit snugly to maximize the space of your bed.
DualLiner sides are made from a high-density polyethylene plastic called HDPE, which is known for being strong and slippery. Conventional drop-in liners are entirely made from HDPE, which leads to weak corners because the HDPE plastic has to be formed with rounded corners where the wall meets the floor, leaving gaps underneath the liner. DualLiner eliminates these weak corners because there are no gaps under the liner.
The DualLiner floor, or mat, is a shock-absorbing 3/8-inch thick ZeroSkid rubber mat, with molded-in soft rubber nibs underneath. This has two advantages: unbeatable shock absorption, which protects your truck from damage, and unbeatable water and air flow, which protects your bed from rust. The HDPE walls meet this rubber mat floor at a 90° angle, which is how we eliminate those gaps.
The aptly-named “ZeroSkid” mat also protects your cargo by grabbing on, preventing it from sliding around.
Drop-In Plastic Truck Bedliners Revealed!
When you first look at a drop-in liner you may think it looks durable and will be able to hold up for a long time. But look closely: a one piece liner has curved corners, and covers the truck’s factory drain holes. The rounded corners reduce the cargo area in your truck bed slightly and leave gaps under the bedliner which creates areas without support. These unwanted gaps underneath the liner are weak areas and make drop-in bedliners susceptible to cracks. Since there is a lot of support in the middle because the liner is reinforced by the bed, the corners receive more tension making them even more vulnerable. These corners are high risk areas and when a drop-in bedliner starts cracking it is usually in these weaker areas. Some, but not all, drop-in liners are a semi-custom fit, which can exaggerate the problem due to poor fitment.
Drop-in bedliners are made entirely of HDPE plastic, like the DualLiner walls. HDPE is also a slippery plastic. Some engineers actually refer to HDPE as “non-stick” which is actually what makes it ideal for pipes and milk jugs and bedliner walls (not floors). This is why many drop-in bedliners have extremely slippery floors, allowing your cargo to slide around and bang into the side walls. The impact of sliding cargo creates more stress on the rounded corners causing cracks.
Another downside of the non-stick nature of HDPE is that the liner, because it is slippery, can slide around on top of your truck bed, causing abrasion damage to your paint. Get the picture? Cargo slides on top of the HDPE plastic and the plastic in turn slides on the surface of your truck bed!
Problems with HDPE drop-in bedliners:
- Stress cracking in corners, accentuated by rounded corners with gaps between the bedliner and your truck floor and walls.
- The non-stick nature of HDPE is great for bedliner side walls, not for bedliner floors.
- The slippery aspect of HDPE also lets it slide across your truck bed causing paint wear.
Spray-On and Roll-on Truck Bedliners Revealed!
Spray-on bedliners are sometimes initially preferred by people wanting rust protection, but may not be overly worried about denting their truck bed. The spray-on liner seems more durable than a drop-in liner because you do not have to worry about it cracking or breaking, or water getting under it. Spray-on and roll-on bedliners are applied directly to the surface of your truck bed. They are permanent once you scuff the paint off your bed to install the liner. Spray-on liners can absorb minor impacts, but if the impact is greater than the liner can handle it will permanently dent the truck bed.
Spray-on liners are also very thin compared to the DualLiner 3/8 inch rubber mat. A spray-in liner can vary in thickness and is often between 0.125 inch to 0.250 inch thick.
Spray-on liners are made from a combination of polyurethane and epoxies. The polyurethane is the protection, and the epoxies are the glue that holds it all together. Spray-on liners must be installed by professionals for a proper job. The chemicals used are also very harmful to people while being applied.
Polyurethane is often used as a wood finish, or in its softer version as a flexible foam in mattresses, seat cushions, and car seats.
Problems with Polyurethane spray-on bedliners:
- Extremely toxic before fully cured, may require OSHA compliance.
- Must have protective eyewear, respirator, and clothing when installing.
- Non-standard thickness; entirely dependent on skill level of person applying.
- Will not stick to a slippery surface (your paint) so it requires sanding of your truck bed which can also void your factory warranty.
- For more problems, simply go to Google and entire “removing spray-on bedliners.”
