I heart Rust-Oleum.
I have used other "metallic" spray paints but they haven't come close to actually looking like metal.
I bought these letters [bottom right] from Hobby lobby on sale. They were $4o all together; more than I thought I would pay but well worth it.
The color when I bought them was a rusty brown color that didn't really go with my vision.
...I know I'm a nut. Jake couldn't stop laughing when I informed him that the metal was the wrong color.
Lucky for me I did some research and read fabulous things about Rust-Oleum.
I picked some up at Walmart for around $4.
2 coats later...finished beautiful metallic sheen.
