What kind of decals are you after?
-That determines the sort of source you are after.
I local sign shop or a autographics specialty could help with normal "cut-out" style vinyls.
A more complex printing may take a different kind of shop.
Company logo graphics, like commonly on import show cars is a bit more complicated, as copyright issues come into play.
The "m" logos on my wheel centers came from a local sign shop and I painted the caps red myself and applied the vinyl after it dried.
Other stuff presently on my vehicle are from the source shown.
I am getting more from Rip Graphix, who is a major sponsor of Scikotics. He does a good job on completely custom, one-off stuff.
thanx . im just looking for something simple like a raceing strips going from back to front in black or carbon like color.. i think ive seen some graphic sign and awning shops around my way i will check them out
