Flooded vehicles can be very difficult to handle, as there can be rust in any and all places. They are best avoided, unless it's the car that you really want. | Flooded vehicles can be very difficult to handle, as there can be rust in any and all places.

| + | ==What's galvanization?== | ||
| + | "Galvanizing" typically refers to hot-dip galvanizing, a process by which iron or steel is coated with a thin layer of zinc, by dipping it in a molten bath of zinc. Galvanized steel can be welded. It's been used for more than 150 years. | ||

| + | Zinc oxidizes when exposed to air, forming zinc oxide, which then reacts with water molecules in the air to form zinc hydroxide, which then reacts with carbon dioxide in the air to form zinc carbonate. Zinc carbonate (the final "galvanizing" layer), is a thin but very tough protective layer. It also acts as a "sacrificial anode". It will corrode before the steel it is protecting. | ||
