Older E140 Altis are prone to sill and floor rust in Malaysia's humidity. Underseal and rust converter treatment guide.
Altis rust prevention is especially important for older E140 units and high-mileage ZRE182 taxis. The underbody, door sills and wheel arches are most vulnerable to Malaysia's year-round humidity.
Rust Prevention Service
- Underbody anti-rust spray: RM 200–400 — apply every 2–3 years on older units
- Door sill rust treatment (if rust spots visible): RM 150–300 per sill — treat early before rust goes through
- Annual inspection: lift the car and inspect all drain holes — blocked drains cause internal body rust from inside out
