Rust Repair and Seam Sealing in Riverside, CA
Cutting out corrosion and resealing seams on high-mileage commercial van bodies.
High-mileage commercial vans rust from the bottom up. Road brine off the Cajon Pass grade, wash-bay chemicals, and standing water in door bottoms eat into Sprinter and Transit rockers, arches, and floor seams. In our Yorba Linda shop we cut out corroded metal, weld in fresh panels, treat the area, and reseal factory seams so moisture stays out. Riverside fleet vans that log real miles benefit most from early rust work.

Frequently asked questions
Why do high-mileage vans rust so fast?
Road brine, wash chemicals, and moisture trapped in seams and low panels all speed corrosion, and work vans collect all three. A van that runs mountain grades or sits with wet cargo tends to show rust years before a garage-kept one.
Can you repair rust without replacing the whole panel?
Small surface spots can be treated and resealed, but rust that has eaten through the metal needs the section cut out and fresh steel welded in. Painting over active rust only buries it while it keeps spreading.
Do you reseal the seams after welding?
Yes. We reapply factory-style seam sealer and add cavity wax or undercoating where it belongs, so water and road salt cannot work back into the repair.
Should rust be fixed before a repaint?
Always. Fresh paint over active rust lifts and bubbles within a season. We make the metal sound and sealed first, then send the van to the booth.
