With plastic “pop-in” bed liners, water and dirt can get trapped underneath the liner, resulting in corrosion and noise while driving. Turbo Liner prevents rust and corrosion by permanently bonding to any surface, without bolts or air gaps. It also deadens sound vibration giving a quieter ride. Plastic “pop-in” liners tend to warp and even crack in extreme weather conditions or from heavy loads. Again, this simply is not an issue for Turbo Liner.
Polyurethane liners are sprayed in many different ways, but one thing holds true about almost all of them they dry slow. What happens when spraying Polyurethane is you end up with a thicker coating in the valleys and a thin coating on the peeks of the bed. The other thing about Polyurethanes is that most of them have a really rough and chunky texture that short of looking bad the texture has no other function. Color holdout is another issue. Most companies don’t use much UV protection in their materials, which causes them to chalk and fade out almost immediately.
Because polyurethanes have such slow dry times the material can run down or sag, pooling up in the low spots leaving the material thin on the main or high spots of the bed surfaces.
With a Polyurea this is not an issue. With the application process and dry times of Polyurea’s the material is applied in an even coat across all surfaces and is dry in seconds.
