I'm a big fan of Rustoleum too.
Not sure if the Rustoleum we have in Australia is the same as the USA product, but I think it is.
It is VERY good paint - doesn't sag, run, wrinkle. (if your technique is OK.) Gives a good solid coverage. Flattens out to a nice even glossy finish - even if it goes on a bit spotty, the high spots "relax" down to a nice even finish. It is the best spray can paint I have used.
I resprayed our ride on mower with it a few years ago, it has stood up well to punishment. One area I spilt some petrol (gasoline) on it when the paint was only a week old, it wrinkled up unfortunately. I will eventually sand and repaint but it is well down my list...
