Rating: +++ excellent ++ very good + good (for exterior application and whenever chemical resistance of the finished powder coat is required, a protective clear coat is necessary to protect the metallic finish from unwanted corrosion process) ○ fair (for exterior application and whenever chemical resistance of the finished powder coat is required, a protective clear coat is necessary to protect the metallic finish from unwanted corrosion process)
