Anyone know the shelf life of U Beaut and Arboroil/Arborwax finishes.I have a stack from an estate that I’d like to give a try. They includeShellawax, Hard Shellac (use before 2010 vintage) and U Beaut Sanding sealer. I alsohave a box full of Arborwax and Arboroil that has a manufacturing date in 2000.The tins have never been opened but I don’t know if the solvent might have lostits ability to set the finish. All advice welcome.
