Rust if the result of a natural chemical reaction between steel and air. It's accelerated by increased moisture and corrosive agents like road salt and exposure to salty sea water. If covered with paint the metal surface is protected from oxygen and moisture - it won't rust. Rock chips, dents, scrapes or anything that breaks the paint's surface can allow oxidation to continue.

Rust is simply the oxidation of iron. 18/8 steel can't unite with oxygen to create iron oxide (rust) without the help of outside elements. The most common cause of rusting on stainless steel is water with a high mineral concentration. If flatware is not completely dried after washing, the remaining water evaporates and the minerals, which were in suspension, settle on the stainless and cause rusting. The rust is easily removed by using a moist sponge and any good cleanser. See similar questions...

It sounds like you have a prefabricated chimney with a rusted chase cover. The top of the housing that is built around many prefab chimneys has a flat metal roof called a chase top or chase cover. Homebuilders nearly always use galvanized steel chase covers that begin to rust-out after about 15-years. Eventually, the corrosion will eat through the metal and cause a serious leak. We routinely replace these rusted-out covers with stainless steel chase covers that will last a lifetime. See similar questions...

The work that is painted will not rust unless it gets deeply scratched. The work that is left raw (Rock Men, Plant Sticks, Garden Sticks, etc.), will rust if left outside or in a damp environment. However, they are designed to rust and look fine in the garden with rusty-earthy tones. If you prefer the color of raw steel but do not want it to rust, you can spray it with several light coats of clear lacquer or polyurethane. See similar questions...

Galvalume coated steel roofing panels are protected by layers of metallic and polymer coatings. Industry studies have repeatedly shown them to outperform the corrosion resistance of other coated metals. They are available with warranty's as long as 50 years. Metal roofs are painted with high-performance polymers that have exceptional weathering properties. See similar questions...

The way we remove rust from machined iron surfaces at the foundry, is with plenty of solvent (or diesel oil) and a scotch brite pad. Wear rubber gloves so you don't dry out your fingers. When the metal is shiny, wipe on a coating of oil to protect it. For areas that cannot be oiled, because of paper contact, try Johnson's Paste Wax. Rub it on heavy, and don't polish it off. It will self-polish, and protect in the mean time. See similar questions...

Rust Converter is a synthetic polymeric formula that converts existing rust into a moisture free, black protective coating. Not only does it eliminate existing rust, but it seals out moisture to prevent the possibility of future rust formation and corrosion. Surfaces protected with this primer and an oil based paint resist the effects of weather, sunlight, rain and even salt spray without peeling or cracking as long as the oil based paint is maintained per manufacturer's recommendations.

Rust Remover will remove rust stains or red clay stains from any surface on your house or boat that is resistant to acid. See similar questions...

How concerned you should be about rust depends on what type of bike you have and where you live and how you use your bike. The worst-case scenario would be an all-steel bike, ridden regularly in the rain, stored outdoors in a town next to the ocean. That bike would last about 3 months before turning to rust dust. On the other hand, if that same bike were cleaned, waxed, and lubed after every ride and stored inside, it might last a lifetime. See similar questions...

Ideally, Rust Converter should be stored at room temperature out of direct sunlight. It should be protected from freezing or temperatures above 100 degrees F. Failure to follow storage instructions will cause this product to gel and become unusable. See similar questions...

For the best results, brushing on is recommended. For larger surfaces, pour on surface and spread with a broom, mop, paint roller or squeegee. See similar questions...
