the only questionable part of that is they generally have no idea how much material is actually being applied. Very few measure wet film thickness. I have no problem with Tru oil - but it's not a "coating" like lacquer or polyurethane. It's an extremely thin oil-based varnish stain, but should not be compared to varnishes either - it provides just a fraction of the protective film a varnish does. Only 14% of the content is resinous oil (the rest is solvent) and part of that oil evaporates as well. About 10% of what is applied to the surface stays there - the rest evaporates. It's a decent material as long as it's being used within the scope of its capabilities.
