I found the thread I knew there was no way I thought of this one myself. Hopefully the link works properly.

Instead of a thin piece of sheet metal, I'm going to use a metal blank electrical box cover. I spray painted it with some Rustoleum primer and then sprayed it with some satin white. I happened to have those two in the cabinet in my garage. I don't think once POP riveted onto the wall it will cause any closing issues, as the metal is quite thin. I will do some double checking before I go doing anything crazy though.
