Bonderized Steel or "Paint Grip" as it is commonly referred to in the gutter and roofing industry is a ready to paint material. If you would like your downspouts & elbows to match a specific color this is your best option as it can be easily painted without applying any special primers or chemicals that would typically be needed to etch the metal in order to accept paint. Bonderized steel is actually Galvanized G90 Steel that has been put through a phosphate bath and has a layer of Chromate applied and dried, this process produces the dull grey color characteristic of bonderized galvanized steel which provides an excellent primer for painting applications. There are some disadvantages that should be considered before using this type of metal. Bonderized steel comes with no warranty on the finish, it scratches very easily and will have small scratches just from the manufacturing process, if it is to be painted then this is not a problem and the small scratches from manufacturing do not affect the paint adhesion and will not be noticed once painted. Due to the chormate coating Bonderized metal should be painted as soon as its installed as white rust can form rather quickly if left unprotected.
