I am at present building an avairy and want to trim it with some deep red mixed hardwood(As a feature). As the avairy is outside the timber is going to be in the sun for a fair period of its life.
Would I be better to go for a poly/varnish product such as sikkens or would I be better to oil it? I know the uv is going to knock the timber around and I wouldnt be worried if I had to renew the finish once a year or so.

Any ideas or comments on which way I should go?

thanks
Shane
