Best wood protectant for trailer decking?
I have a new trailer with wood decking that is pressure treated 2x8 planks. The wood decking looks fine now, but I want it to stay that way indefinitely. The trailer has to be parked outside beside the garage where the water from the eves of the house drips on the trailer, so it gets wet every time it storms, and stays wet most of the winter due to snow melting on the roof and dripping on the trailer. This is the fourth trailer I've owned, and all of the others had the planking start to shrink and warp a small amount, even though they were also made of pressure treated wood. I want this trailer to stay nice if it is possible.
What is the best preservative / protectant for this kind of wood? What about good old fashioned linseed oil that they use on log cabins?
