It's called Rub'nBuff Wax Metallish Finish. I got the antique gold color to try out at home. It says to use your finger to dab onto surface or to use a dry cloth, but I opted for a short bristled brush. Side note- it has an odor and you must clean up with mineral spirits. That means it's the real deal, baby! Ha. I decided to try it out on our pictures in the half bath.
Here's the results- it really does look like gold leaf. It's got sort of a dull shine to it, even if you can't tell from iPhone pictures. This stuff was cheap and you really only need a small amount. It's much like Elmer's- a little dab will do ya.
And just like that, our half bath got a metallic face lift.
