I use Dulux Woodsheen, it forms a polymer waterproof coating over smooth-finished wood. So no chance of it "bleeding" if wet. The wood frame covers to my indoor hospital tank were painted with it twenty years ago. The atmosphere is always moist because of the amount of water in this room in my garage and I've the filters for the pool in the same room, so the wood does get quite damp.

Digressing a bit here,

It's a versatile wood covering and I think it makes wood quite attractive.

All my exterior wood fabrications, pergolas, tea-house and shed are built from softwood (hardwood is terribly expensive and not that "hard" these days) and have been coated with Woodsheen. I give them another coat every three years or so. This tea-house, I built of softwood and roofing ply, (I took this photo last year after I'd changed the roofing felt and made a new top opening skylight) is 25 years old and all the wood is still sound.

I've also used it on this rough finished eight foot security featherboard fence and door, between the house and the garage. (The only way into our garden apart from the French windows at the back of the house). It's still effective but doesn't go so far as it does on a smooth surface.

The garden shed I built which is a softwood frame clad in roofing ply must be 35 years old, that as you can see, is showing no sign of rot either.

The stuff comes in a variety of colours, (I use mahogany) but it ain't cheap, nearly forty quid for 2.5ltrs, but I find it a great investment. With successive coats it goes darker and the finish which is gloss dulls down as it weathers so ends up sort of "eggshell" in texture.
