Normally not if unopened. Once opened 50/50.

fast)?

No clear finish will keep wood from turning grey, that I am aware of.
UV rays fade the surface of the wood.
Pressure wash or sand to remove the grey.



I'm making some planter boxes for SWMBO (pictures coming when I'm done) and
wondering what I could use to keep the grey away for as long as possible. I
don't think there will be any ongoing maintenance, but if I can toss on a
fews coats of something to at least keep them looking new for longer, I'd
give it a try.

If you wan to still see the wood, use an outdoor stain.

amongst her other plants.)

Thanks!
