After reading in lots of place I decided to use tung oil on my bass that will be built. But the thing that I don't know what is the tung oil .. I went to check a big market: Bauhaus (the one you know where you can find 100 different type of hammer , construction tools, paint, guys looking to drills with smiling face, the same face of women buying shoes etc.) I asked if they have Tung oil and I tried to explain that I'd use it on an instrument the only thing they offered me was a can with a "Wood oil" label, the other writings were in german and I hardly know a word in german. Is it the same thing with Tung oil? What other name can "Tung oil" have, I mean is it a natural liquid or something produced with some chemicals (if so what are those chemicals as I can check if that can contains those chemicals). Maybe the german name of "Tung oil" can be helpful as the market being a German brand has lots of thing from Germany.
