Under-wheel-arch corrosion — treatment with mud flaps

Tags: #corrosion

Corrosion under the wheel arches — common in damp/salty climates such as St. Petersburg — can be slowed with universal mud flaps installed using self-tapping screws, at roughly 500 RUB per pair (RU market, April 2026)¹². This prevents further water spray and rust progression going forward, but it does not reverse corrosion that has already formed — it only halts new damage. See the cabin-water-leaks card in this section for related water-ingress causes that can accelerate this corrosion.
