That is some awsome ability Revolution...design choice and depicting it on the substrate.
I would like to offer a few thoughts for custom paint...get a second set of panels for artwork, accecpt the fact that they will get damaged at some point, and be willing to pay for quality work.
3-4K for a bike and 8-12K for a car is not that high. Painting is the easy part...prep / materials and having a clean evironment is what can be expensive.
It is nice to have a personal / uniquie scheme.
