Thumper I second what my man Socal said, if you don't add the clearbra you will soon notice nasty visible chips ALL OVER your car and it will probably be more expensive than installing the clearbra from the get go.
The trick is to go with an established company with experienced installers and get the right clearbra. Mine is pretty much all over the car except the roof, it looks great and IS barely noticeable. I have to look for it and point out for people to even realize the bra is on. DO IT MAN, DO IT
