Once I got my product I was deciding on where I should put my decal. I decided to install my decal on my from windshield on the top center mount due to my louvers being installed on my back windshield. I had first prepped and cleaned my windshield and place right on the top of the windshield. It was a easy install and there was no hassle! This is a must! I am getting noticed more for my Instagram page! Great purchase!
