I have had my stripe on since early 2003. I use it all year (snow, salt, sun) and have done nothing special, but always wash by hand instead of car washes. This year it is starting to look a bit flat, and the edges are getting rough so I am planning on removing and redoing them in the spring. Mine said they were good for 5 years, and they were right..
Here's the video I was telling you about. I have another one that I'll post later today too. [ame="http://www.youtube.com/watch?v=WiyR339tIDE"]YouTube- Driving the Mini Cooper S over East Canyon[/ame] You can see how the stripe makes me faster. dp
