i don't think that this "tint king" is part of a franchise.
as far as i know it is a sole proprietorship; the owner added the tint for my first three vehicles, the cx-9 was the first time someone new was there. (owner showed up later)
this is also the first time they gave me a warranty card to fill out; which i wasn't sure how to take.
my mustang was tinted there in 2006 and no fade. it is garaged, though. my wife's car was tinted there in 2008 and no fade so far. also garaged but sits outside much more than my mustang which was a garage queen for a long time.
funny thing is they try to get me to upgrade the to a more expensive (fade free) tint every time and i always refuse. i tell him the "cheap" tint has yet to fade!
