Anti-Rust Coating for New Cars: Essential or Waste? Know When to Get It Done.
- •Anti-rust coating is a protective layer applied to a car's underbody, wheel arches, and chassis, available in rubberized, wax, oil-based, or polyurethane types.
- •In coastal cities (Mumbai, Chennai, Goa), salty air accelerates rust; waterlogging during monsoon and mud-stones on rural roads also cause damage, making this coating beneficial.
- •It provides protection against rust, keeping the chassis, brake lines, and suspension strong, reduces road noise, saves repair costs, and improves resale value.
- •Poor application can trap moisture inside and accelerate rust; never apply coating over existing rust.
- •Only get this done by a professional workshop on a clean, dry, and rust-free surface; pressure washing and degreasing are essential.
