c5alive has been selling the same yellow side stripes for a number of years now, before I took over the site in 2008. It is expensive tape, but seems up to the job and I'm very happy with what we use. As an additional test, I tend to fit the offcuts to my motorbike (which is used all year round,in all weathers, 70miles a day) and it has stood up to some serious abuse so I feel it is more than capable of surviving on a c5.
There has been a concern raised that trimming the tape causes damage and allows water ingress/deterioration of the tape.
This is not something I've seen happen to any of the c5's that I have fitted the tape to, so do not see this as a problem. The stripes have been on Moneypit and Dave for quite a while now - the only damage I've seen has been caused by scraping against kerbs,walls etc. and these c5's have been out in some horrible weather (rain and snow) and get washed with a hosepipe regularly.
Has anyone experienced problems with the tape ? I don't intend to seek an alternative until I'm sure there is a problem .
