Rust Repair and Undercoating in Corona, CA
Rust cutout, metal repair, and protective undercoating for box trucks and vans working in Corona and the Inland Empire.

Frequently asked questions
Can you stop rust from coming back after repair?
Yes. We cut back to clean steel, apply rust converter and epoxy primer, then seal seams and undercoat the area so moisture cannot restart corrosion under the surface.
Do you undercoat new box trucks as prevention?
Yes. Undercoating a clean truck early is the cheapest corrosion protection you can buy. We coat the underbody, wheel wells, and cavities before rust ever starts.
Is a rusted box truck floor worth repairing?
Often yes. If the frame is sound, we replace the rusted floor sections with fresh steel, seal the seams, and undercoat, which costs far less than replacing the whole body.
