I purchased a precut window film package from an online dealer for my 07 300 touring. I have the film for all 4 doors, I was going to attempt myself but chickened out. I have an appointment to get them done by Formula one in NC. They wont use my film they said, so I was going to offer it up to anyone that wants to make an offer. It's 35% and laser cut, you just need to follow the score mark around the film to get it perfect. The brand is solarguard.
