LOL, if you didn't know it wasn't vinyl, you wouldn't have ever known otherwise. You certainly can't tell it's canvas from this photograph?
The wrinkles on your install are accented by the sheen of the vinyl, which is another reason I prefer the matte look of canvas. Notice how much better "Jaws" install looks with no wrinkles. Bad installs do nothing for the looks of these old cars except to make them look cheap.
