For half-assing it.
Come on, matte wrap that black on the back and the roof/buttresses. All or nothing.
I would like it a lot more if the car and rims were gloss coated but the matte sides and rear "911 section" mixed with gloss on the flying buttresses, roof, remaining black section of the rear, etc...looks unfinished at best.
The "car of the future", "paint-scheme of the past".
But, for real, it was in to check a grounding bolt on the gas tank that may cause a leak when improperly installed (mine got the all-clear Friday, no replacement gas tank necessary).
