== Answer == Parkerized finish is a non reflective matte type finish (black). It is used on military weapons to prevent reflecting sunlight and giving away a soldiers position. It is also called a phosphate finish.It is produced by a chemical reaction with the metal itself rather than being painted on.o finish is a verb meaning that you have done something and you have completed it. The noun finish is the completion of a project, or the end line of a race.
The Bonderized steel should be painted immediately after installing to prevent the phosphate coating from developing white rust. The galvanized steel is first cleaned and rinsed and then has a conditioning agent applied to form a fine crystalline zinc phosphate coating. By doing this, the process turns the bare galvanized surface to an inert, crystalline zinc phosphate which then is rinsed and sealed with a dried chromate coating. Bonderized steel is popular in the rainwater goods industry. Typical uses are, rain gutters, downspouts, roof flashings, and roof valleys. This zinc phosphate finish is a perfect surface for painting of the fabricated material in the field.
