Chrysler offers spray bombs in Race Hemi Orange (they used to anyway) it's pretty close in shade but the stuff I bought comes out of the can as thin as water and as mentioned takes a ton of it to get good coverage. I wouldn't reccomend it but at least it's close to the right color as opposed to Street Hemi Orange.

Frank sells his in cans (not spray bombs), it goes on very nicely, I use a touch up gun and give it one light coat followed by one moderate coat over bare (very clean) cast iron and it works fantastic
