I don't understand the difference, in terms of longevity and appearance, of painting a sheet of perforated steel with black paint from a spray can, or having it powder coated black. The holes in the steel are very small diameter (1/16") and close together (1/8" centers). This sheet of steel "screen", about 3' by 4', will be going into a screen door, replacing the older and deteriorating mesh screen currently there.
I'm concerned about some of the holes filling with paint, but that seems a risk in either case.
On what basis would you decide between these two approaches to coloring the raw steel black? Do you have other suggestions for this project?
Thanks.
