All wood has the ability to lose and gain moisture based upon relative humidity. Paint and other finishing products only slow down this exchange, not stop it.
All Cedarshield wood preservative products use the same boilerplate information to describe each of the six wood treatment products. Let us for discussion sake say products work as described.
Went to the Testimonials did not find one review of "Turner's Choice Stabilizer. Reviews for wood treatment products just not believable, what kind of finish will you use on your pen?
For outside wood applications not requiring painting or other finishes applied these products might be okay. I do not believe the one time application and lifetime guarantee. I do not know of anything that will not expand and contract do to hot & cold and weathering.
While you may be able to apply a stain to wood after treatment with Cedarshield, not so sure about other finishing products like paint or clear finish products. If you have ever tries to refinish wood that been polished with silicone product you understand what am talking about. Same goes for repainting a car. You have to take extra measures to get a good re-finish.
The review provided by Bob Littlejohn, MBA. He and his friend applied three coats "All Natural Cedarshield Oil Wood Preservative," to a slab they cut off a log. That slab was ready to work by the time they got back home. Nice story but no pictures, raise the arm and save the watch!
