Great link Ken . I have 4 guys in my car club with matte finish I hate cleaning them. In my opinion I would never get a matte finish they are not fun to maintain.
I find Scholl concepts no gloss series NOGLOSS - Matt Surfaces Care System and Permanon Matte http://www.permanonusa.com/Supermatte.html and Permanon platinum to be the 2 best options by a mile.
definitely a well written article. best one i;ve seen to date as well, like mentioned above. they must have consulted a pro detailer...they got the grit guards, SV products, Dr Beasley's products, and even the CG matte detailer.
I actually saw a matte grey Veloster over the weekend. It was fantastic looking. Good on them for going to an expert to make their guide.
I would love to own a matte vehicle just to wash and wax it like a non-matte vehicle. Just for the hell of it.
