Best thing to do guy's is go to your local Signmaker - They use a stuff called Vinyl (Basically - it's a thick glossy sticker material that you see on vans/trucks etc.) It can be printed on and better yet it can be cut exactly the way you want , including where the controls are!!!
What you can even do is bring along your own artwork or good quality copies of original artwork.
Printing this way may be a little more pricey, but I guarantee the results are durable(Scratch resistant!) and top quality!! I't what I've used on my Cab.
