I'm looking to tint my windows. I've got an '03 GGP. Could someone explain to this tint newbie what kinds of tint there are, quality, levels, warranties, brands, etc.? I live in STL. Law is 35% on fronts, anything on rears. 35% reflectivity on front and rear. I was thinking about going 35front, 20 rear.....but then ofcourse all these other questions come up. Thanks!
