Does water get under the mat? And does it cause rust issues?
The truck manufacturers have spent millions of dollars on perfecting paints for vehicles. Just like the outside of your truck, the bed is designed to shed water. Your DualLiner® does not interfere with the drainage holes provided by the factory. In contrast, a spray-in liner requires your paint to be sanded for proper adhesion (like any other paint), effectively destroying the integrity of the factory paint – and voiding the factory paint warranty. Rust could form if you damage the paint in the bed. However, the DualLiner® provides better protection than any other bedliner.
