Faux weathered finish

"Weathered wood" is one of the latest crazes.  Not my thing, but if you have a "customer" that wants something here are some options

Or you could just leave it outdoors in the sun and rain for the summer.

I have found some of the "barn wood from a Scottish farm" (really had one of these) and the like very susceptible to stains and splintering.   I would often get asked, "I like the looks of this wood but can I protect it with 'a coat of poly'?"    Well, yes you can, but it will never look the same.   I'd always say (to myself) that one errant meatball, drippy burger, or spilled glass of red wine and you'd have a stain that you could not get out.  And I had a few customers that experienced that.  Remember the three objectives of a finish --

• beautify
• protect (from wear, damage and stains)
• make a cleanable surface
