The color of the paint will age to match the rest of the metal piece over about a year. Finally, apply a zinc-rich paint over the affected area.Rinse and dry the affected surface once you have removed the last of the visible rust. Let it sit for 5 minutes and look for rust. Paint the solution of naval jelly and water on the areas of rust.Allow it to sit for about 10 minutes before moving on the fourth step. Don’t splash the solution while you are mixing it. Put on your goggles and gloves and make a solution that is about 5 percent naval jelly and 95 percent water.It’s not really a “strong” acid, but it can still burn your skin and eyes. The reason you need the protective gear is that naval jelly is just the common name for phosphoric acid. You will need protective goggles, rubber gloves, and naval jelly. Now you can begin your repair process.Then rinse off the steel with a garden hose and allow to dry again. If you still see rust, repeat the first step. Next, make a second pass over the rusted area. Rinse off the loose rust and dry thoroughly. Pour some vinegar on the rusty spot and then rub off the rust with a wire brush. But here’s what you need to do to prevent further damage: Most of us won’t do anything to protect metal before we see reddish-brown rust. Exposed steel will rust much more quickly from the more familiar reddish-brown rust. Eventually the zinc carbonate can flake away and expose the steel beneath it. If that metal is underwater or exposed to water on a constant basis for a long time, the zinc coating begins to react with the water and the carbon dioxide in the air to form zinc carbonate, which is off-white. Galvanized metal is coated with zinc that gives it a green patina as the metal is exposed to the air. Here is what to do if you start to notice white rust develop. But, when galvanized steel is in constant contact with water, it can develop a kind of corrosion known as white rust. Galvanized steel is even used to touch up boats, storage sheds and chain linked fences. Galvanized steel shows up in numerous everyday applications.
