I have used a few on my Jetta's,but none of them held up.They were bought at Canadian tire,so I think it was made by Auto Ventshade or something.
You can use a special clear vinyl which applies right over the paint,and is almost invisable,and it protects from stone chips.You can use it on the hood,rockers,or anyplace you need protection.I have a supplier who carries it if you want to try it.
