Coating a Decorative Sheet Metal Heat Shield

++++

Hi,

I have a 40"x60" 26 gauge piece of sheet metal that I purchased from a machine shop in town. I've installed it behind my new wood stove to 1) protect the wall behind it and 2) deflect the heat back into the room.

I really don't like the look of it and wish to "antique" it. The shop told me that I had to wash it down with vinegar first. Then I could do "whatever" to it. I was thinking maybe to take a broken brick and scrape the sheet metal. Then, I'd spray a base coat of red heat resistant paint and then wipe the excess off making sure to get the grooves. Then, I figured on painting a top coat of black heat resistant paint and wiping the excess, too.

Before I go hogwild on this project. Does anyone know if this'll work or will I ruin the sheet metal? If it won't work, does anyone know another way without having to get acid as I'm not really comfortable working with that.

Thank you for your help.

I wonder if you ever found a solution to your problem. My situation is identical to yours.
