The pre-oiled Teak option is ready for exterior application however the Raw option needs a protective coating applied first.
Where abouts are you located @herno
where can I buy this product I am in Qld but it doesn't show up when I search the store?
You might like to check out our range of Castelation Cladding which will allow you to achieve the same look as @ProjectPete's benchtop. From that range, it appears 81 x 26mm Castelation Screenclad is a close match.
Pete also mentions that he's a big fan of the half-dowel styling. You should find this guide useful: D.I.Y. Dowel feature Wall.
Bunnings have some great options via Cedar Sales and Glosswood @artrato3, and the half-dowel design as Mitchell suggested is a nice way to go and readily available from Bunnings. If you specifically want the Bamboo S-Panel profile I've used, I can get you in touch with your local supplier - just shoot me a private message.
