Hi
After scouring the globe, talking directly to Cessna and their original supplier 3M, we were unable to locate or find a suitable alternative.
Never being one to give in so easily, I found a company in the USA which supplies wood trimming, and by luck they also do PVC woodgrain trim. I purchased a 50ft roll of PVC from them for around $94. The only thing I had to do was trim it to the correct width.

The guys name is Steve Kitts.
Item no:12126555175
I will attach a photo, the actual colour is a little lighter than in the photo. It is slightly different to the original, but I was replacing all not just the odd one.
Once I had the strip cut to width, I then glued it in place with 3M contact cement. Looks brilliant against the grey interior.
Anyway this is a good workable alternative to the original from Cessna.
