I'm going this route for my tailights and 3rd brake light.Lamin-x
They have different color vinyl for any use.
I figure I can get a better fit by myself being that I deal with the graphic arts and art in general.
I had to cut everything to precise measurements since I was 17 and even before then.
That vinyl will be cake to me and the price doesn't throw me off because I know I will do it right and my paycheck will take care of it.
Other's may as well go with Andy's overlay's. High quality products and a great person.
I had them and they were great.
