Mercedes-Benz bodies are zinc-coated from the factory, but that protection is only as good as the paint and underbody coating over it. In Dubai, high humidity near the coast, salt in the air, sand blasting the underside on desert trips and stone chips on the highway all wear it away over time. Older models, and cars that have had accident repairs, are most at risk. At Orange Auto in Al Quoz and Nad Al Hamar we lift the car, check the underbody, sills, wheel arches and seams, treat any surface rust and apply protection to the exposed areas.
On the lift we check the sills, jacking points, wheel arches, subframes, brake lines and seams for coating damage and rust.
Sand, mud and salt deposits are washed off and the areas are dried so treatment can bond properly.
We show you what we found and quote the treatment, separating surface rust from anything that needs body repair.
Surface rust is removed back to clean metal and the area is primed to stop it spreading.
Protective coating is applied to exposed areas, keeping it off exhausts, brakes and sensors.
Where needed, sills and seams are treated so moisture cannot sit inside them.
We check drain holes are clear, clean any overspray and show you the finished work.
Rust on painted panels, such as around the wheel arches or bootlid, is handled as paintwork. See Mercedes denting and painting.
Cars parked near the sea, driven on sand, older models and cars with past accident repairs benefit most from an inspection.
Chips on the bonnet and sills expose the metal. Touching them in early stops rust from creeping under the paint.
Corroded brake lines and fixings are a safety issue. We flag them and quote replacement if needed.
Exhaust parts are not coated, as they get too hot. Rusted exhausts are repaired separately. See Mercedes exhaust repair.
Do new Mercedes cars rust?They are well protected from the factory, but chips, sand and salt can damage that protection over the years.
How often should the underbody be checked?A yearly check is sensible, or after desert trips and accident repairs.
How long does it take?Usually a day, depending on how much treatment is needed.
