About done with a cedar planter box, but don't know what to finish it with. It's mostly whitewood. I don't think I really want to stain it, but would like to protect it from graying and accentuate the wood grain. At the same time, don't want to use anything that will harm the plants inside. Plan to line it with plastic sheeting and fill directly with soil after it is protected.

I've read about CWF, but have never used it. Any suggestions/recommendations?

Thanks,

Rob
