After reading many excellent guides to installing the stripes I bit the bullet today and stuck them on. I think I did alright, they don’t look obviously mismatched though I am sure a tape measure would tell the truth.
Turned out to be really easy, if you fancy doing it yourself the best advice I can give is use plenty of soapy water on the vinyl back, and the paintwork. I squeezed out the soap with the squeege naked, not wrapped in a cloth as suggested, and it worked out fine. I can’t see any air bubbles and have already done a few miles with them on and they still look attached. Its like my already super car got even super-er!
