Many drivers assume a brand-new vehicle comes fully protected from rust — but that’s rarely true. Factory finishes focus on appearance, not long-term corrosion resistance. The undercarriage is often left with minimal protection, leaving exposed welds, seams, and metal components vulnerable to moisture, road salt, and grime from the first drive.
At Dent Worx Kingsport, our undercoating and rust treatment go far beyond what the factory provides. We clean, seal, and protect every surface using professional-grade coatings that bond tightly to metal and remain flexible over time. These coatings repel water and salt, preventing oxidation before it can start — something factory primers simply can’t do.
