I want to install leaf gutter guards and have found some that are galvanized steel mesh, in 6" x 3' lengths. The problem is that they are rounded and can be see from the street (I have a ranch house). I read that they could be painted, and I would like to paint them a color that blends with my shingles. I have heard that you need to "etch" the galvanized metal before painting. How do I do this?
I am considering using Behr Ultra Exterior with the primer already in it. It is only for the gutter guards, so if it isn't perfect, I won't mind too much. I just want to make them "disappear" on the roofline.
Any advice will be appreciated.
