Very nice. Have you tested this vinyl in the wild? Have you considered laminating the vinyl before wrapping? I know that matte black tends to show any little smudge or oil stain or anything pretty badly and it does not come off easy. This is where something like a matte laminate will help protect and make it easier to clean it up. I also think that the 5-7 year outdoor lifespan is with it being laminated. The matte black is a pigmented vinyl, and very thin.
I think this is what they recommend for that vinyl: -1340 3M Scotchcal Matte PSA Laminate
GL with the project, and take your time. I know a few vinyl wrappers, and they say the matte black is always a challenge for them.
