... of copper and nickel form more protective rusts. These steels do rust, but more slowly than ordinary steels. This has led to their use in architecture and sculpture. Direct oxidation of most metals in the absence of water occurs only at high temperature. It might seem that high-temperature oxidation...

..., however, metallic shot and grit will usually impart profiles within the 50 to 115 μm (2 to 4.5 mils) range. Such surface roughnesses are suitable for most coating systems. Cleanliness is essential in the preparation of a surface that will receive protective coatings. Paint applied over rust, dirt...
