A can of paint or spray paint can go a long way to resurrecting or improving something. I’m a true practicing believer!
All of our floor vents were pretty much dented and un-salvageable with the exception of our large air return grate in the living room. I bought one rattle-can of satin black paint and went to town on the current grate and also sprayed the new white vents. White vents on a dark wood floor are no good, but black looks great! It was quick and easy and makes such a difference!
