How to make a guitar have a prs blue jean finish?

-Send it PRS' PTC, since they can can refinish stuff and more like a boss.
-Don't know of anyone off the top of my head that offers refinishing services apart from PTC, so I can't help you beyond there.
-Trial and error.
Box it up and send it to the PTC. Or just drive it up. Raleigh, NC is only 300 miles south of the factory.
