I've just made a picket fence, with H3 treated timber (this is treated for above

the natural wood look).

I don't know about linseed oil outside. I think you would have to keep
applying it every year.
My picket fence is really easy to paint because each section is hung
on large screws and can easily be lifted off for painting. I rest them
on old sheets of corrugated iron and spray paint the fence, which is
20 times quicker than hand painting.

I don't like the idea of annual applications.

My fence is all nailed together, no sections. Hand-made!

I guess the spray-painting idea is still possible, with a sheet of corrugated
iron for example, by leaning it up against the other side of the fence to catch
the excess spray.
