Not sure who needs to hear this, but I've been looking for a vinyl wrap to match Super White (I wan't to buy a scooped hood this summer and don't want to bother painting). I heard that Avery was the closest match, so I ordered a sample along with a 3M sample (Vivid, the other big vinyl company, didn't offer samples). After comparing them on the hood of my 4R, I can say with confidence that 3M's glossy white is the closest match. Avery is too bright, more white, if that makes sense. That being said, it could be that my paint is discolored or something. It's a 2016 in relatively great condition, just as a disclosure. Is it 100% perfect? Not really. But I doubt that anyone would ever be able to tell. Maybe if you asked them to find the off-colored panel they could identify it and even then maybe not.
Anyways, here's mine at sand hollow reservoir in southern Utah with the family dog.
