   No!

    Danish oil will quickly be gone providing no protection at all!

     Here's the problem.. all good clear finishes have a measure of gloss. The only real protection will be from a paint..

      I know! But all the exterior timbers on my place are black walnut and trust me I've done so much reseach on this subject I could write a book.

    Next best is a marine spar varnish.. The best one is a brand called Eppiphanes.. when you look at the price though it will really make you swallow.. then read the instructions on the side of the can and  that will really cause you to gulp!

    Other brands such as interlux etc.. aren't as durable but they are a fraction of the price.. Only one marine spar varnish to really avoid and that's Minwax's offering. 

    Your best chance to get any sort of durability on this is to give it a coat of shellac first..  then a brief sand with 220 grit paper to simply knock off the nubs that are raised from the shellac.. followed with a second coat.. let that dry an hour and apply the spar varnish over that..

     The more coats the greater the protection. However about 5 years is the absolute most you can expect even using Eppiphanes with 5 or six coats.

   The problem with any exterior finish is that UV rays will degrade it over time. And once the finish is degraded, then the wood starts going.

   A solid paint offers the most UV resistance, but that's obviously not an option.

   Choose a marine varnish with a UV protector. And one with lots of resins, to maintain flexibility.

   But if you get 3-4 years out of it without having to re-coat, you'll be doing well.

   Let your customer know that as soon as the finish starts hazing, or the wood gets gray, its time to re-coat.

   Better yet. Treat it like a boat. West Systems System 3 Epoxy with a SATIN Spar over. The Spar slows the UV degradation, but the epoxy will maintain the wood WHEN the Spar fails, not if.

   Being as most don't catch it in time, or properly keep up on it, the epoxy buys you (them) some saturated fiber time. That keeps the water at bay while the spar is being reapplied.
