I'm making some raised beds and using freshly milled pine. I know there are better woods around to use, but a great mill in the area sells pine boards for a great price. I hope to get a few years out the beds. I've seen freshly milled pine last a long time with nothing on it, even close to the ground.
To extend the life of them I was considering using tung oil and citrus solvent to coat them, might add a couple years to them. The cost of the oil and the pine is far below any other wood choices around. I'm pretty familiar with working with tung oil on dried woods and have finished quite a bit with it.
I am looking for opinions on whether or not the tung oil would work on freshly milled pine. I imagine they won't soak up much, but it seems like the tung oil would at least create a pretty good film on the boards, especially if applied thick, as in less citrus solvent or close to none. But maybe the moisture of the wood will cause the tung oil to not stick at all. Anyway, any opinions welcome. Thanks
