We used John Deere Blitz Black on my son's Studebaker wagon. The paint job is 20 years old and has only been inside a few nights in that time. With a good wash and a little TLC it would look almost new. I used Rust-Oleum flat black on my '53 pickup in 2012. It didn't bond well and never really hardened. Where I tried to touch it up with the rattle can version it turns gray and simi gloss in a short time. The truck looks like crap. It looked so good when we did it. I hate paint!
