I hate to point this out, but are you willing to pay for the hours of hand labor it will take to get rid of that orange peel and have a dirt free clear coat?
Paint booths in the factory are nearly hermetically sealed and are almost static free. They have environmental control systems in them that are almost what you find inside a nuclear submarine. The paint is applied by robots and is negatively charged and the car is positively charged so they don't have to hand work the finish to get out orange peel.
I've yet to see a paint booth in a dealership or aftermarket shop that is that advanced. They simply can't afford to have that clean of a setup for paint when they are only painting a small car part or a single car in a month. Hence the hours of wet-sanding by hand to smooth out the peel, then more hours of work by hand to lay and clean up the clear coat.
