My Challenger needs to be redone. Any advice on paint brand to use and what process to follow?

I'd love an original single stage enamel but I realize that may not be practical. I try to only drive the car in nice weather but I do drive it as opposed to trailering it. It doesn't get washed unless I get caught in the rain. I do use a spray shine on it and a California duster.

Thanks for your opinions and advice.
