I'm making an outdoor bench from walnut. The description of OSMO UV Oil says that it shouldn't be used on horizontal surfaces where water may sit and soak in. It says use the decking oil on horizontal surfaces for water resistance. Before realizing this I applied a coat of UV oil for its 12x UV protection. Is it possible to apply a coat of OSMO decking oil over the UV oil to get both the 12x UV protection and the water resistance or am I stuck sanding and starting over.
