Stones and gravel are kicked up hacking away the galvanizing protection from the factory leaving bare metal exposed. Where’s the proof? Open the sliding doors of some 3 to 5 year old mini-vans and you’ll see the evidence! Also, consider the amount of bombardment the under-body of a vehicle endures. These areas are precisely where rust starts to form on a vehicle in its 3rd or 5th year on-ward. Every time a piece of sheet metal is cut or welded in the manufacturing process, the galvanizing protection is lost thus creating a rust-prone area. Galvanizing is a process whereby steel is dipped into a liquid metal (zinc), thus forming a barrier between the steel, moisture and air. The steel that is used in vehicles is galvanized which does provide protection. Where’s the proof? Leave the cover off your barbeque for a couple of seasons left exposed to the environment and you’ll see the evidence! Even stainless steel barbeques have regular steel used in the support frames and that’s where you’ll find the brown stuff start to form. The chemical process that occurs is called oxidation. Steel contains iron and when exposed to air and moisture, rust will occur. Rust is nature’s way of returning a man-made product such as steel back to its natural state - iron.
