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.


Sounds like one of those things that looks good on paper, but won't work
so well. Seems like you have a choice between plugging some holes with
paint or leaving spots of steel unpainted and eventually rusting. Is
this for security?
