I've been thinking about tinting my windows soon. I'm getting 32% up front (cops are giving tickets for anything not legal) and not sure about the back yet (I've got the "privacy rear windows" w/ factory tint). I like the look of the tint, but I offroad... a lot. I was wondering if it would screw up my tint a lot if I rolled down the windows after they were covered in mud. Would it scratch up the tint? Would I need to keep them closed the whole time until I wash the windows off again? I'm hoping to get them tinted soon, so any help is appreciated. Thanks, Bryan
