lot of the steel and aluminum siding out there has been around for a while, and after withstanding the elements for so many years, the factory finish could have become chalky and run-down. It may even be peeling off. Old steel and aluminum siding sometimes gets what's called "surface oxidation". This happens when bare metal becomes exposed due to extreme erosion of the original factory-applied coating. The siding may still be in good condition structurally, but chances are the factory-applied coating is not. Many of us realize that our siding looks beyond its "maintenance-free" stage - the factory finish is most likely faded and chalking heavily and generally looking run-down - but we don't want to go to the expense of replacing it.
