Just a heads up, when working with Danish Oil (a tung oil blend), I found that "turpentine" and "white spirit" are not quite the same thing. Turpentine is quite a bit more sticky and greasier than white spirit. The white spirit is more volatile and evaporates quicker. It is not as volatile as lacquer thinners though. White spirit and turperntine have a similar smell, although the turpentine is a bit sweeter.
I sanded my final coats with white spirit which worked better than turpentine in my opinion, the turpentine was too grease and left a residue.
The only place I found that carries white spirit is Hardware Centre in Strijdom-Park. They also carry the superfine steel wools and very fine sanding sheets. Not a bad place to visit (Not sure if Nelspruit has a stockist).
But then I see that Tru-Oil is a linseed-based blend, so I'm not sure if any of this applies.
