I have that gauge set but I left mine as it came. I think because of the radius around the gauges, you would have to cut the decal larger than the openings and the black plastic would show. For that reason I left mine as is.
There is a water transfer hydroprinting of parts but I am not sure how you would keep it off the outer bezel.
This would be a good option too. To keep it off the outer bezel, I think they'd just tape it off before dipping it but I'm not sure on that. I had some interior trim refinished by a local hydro-dip company in one of my previous vehicles. The parts turned out really nice.
