I'm with Denny on using a roller, besides a cheap gun would do better.
I've shot rustoleum on restored gas pumps to give them an original look and it works well. I've got one which I did back in 97 still sitting outside, but the shine is gone. I used to wax it every year to maintain the shine but lately have not.
All things considered, you get what you payed for. If weathering is of no concern use straight enamel.
I think the rusto held up okay but I'd rather invest some more money for better paint so it will last longer with less work.
I'd leave the Reds alone cause they really fade out. I did a trailer with red in 95 and it looks almost pink and I don't have time to wax a trailer.
As far as rollers go, I've used a real good paint brush and got results that far exceed what a roller can do.
