Depending on which Rust Stop paint they had it was either listed as Solvent or Oil based for some reason. Even if it wasn't the exactly same as Rustoleum it should be pretty close, they even had all the popular Rustoleum colors under the Ace label, Harbor Blue, Regal Red etc..

I got some of the Safety Green to practice, i'll post some pics to show what it looks like on a panal when I can get to it.
