CWF vs. Wolman
"IF" these are the only two choices I have I would only use the CWF-UV or the Wolman F&P in either case I would make sure the customer sees a test board or sample first as both products clear or natural tone appear darker on the average. Of the two I find Wolman to be a better product. If this were me though I would do as Mike says and use the Cabot 3000 Natural or look into their new Timber Oil Natural as I have had GREAT results with this product line. Hope that helps just my opinion.
