Rudy,
I have had some stuff done at "Fastsigns" - there are many locations. They do vehicle graphics.
Additionally, there was a great place somewhere on Rt 64 near... Glen Ellyn? Bubblehead will now.
The guy was great, he did my Vettewrench windshield decal. I will bring my car to him prior to Chevy-vette-fest so my car screams "digitalcorvettes.com!"
I'll try to dig up the name/number.
