Check this site there is a strong warranty with this company, I'm using it on my 2002 boxster no problems so far.
I had the bra installed on the bumper, hood, over the fenders, and mirrors. Paid 500 + tax. It was better to find an installer and have him do the work, than ordering the material and do it my self.
Good luck, here is the site.
Tks. for this info .I checked the site looks a good product but I'm not aware of it in Oz. however will contact 3M here.
Howlong have you had it and what colour is your vehicle ,is the edge noticeable?
Cheers
