It seems SWIM cant find anywhere at any store a suitable naphtha. SWIM recently bought "escort cap fuel" that says it contains naphtha petroleum and tried an evaporation test on it only to find out that it left the slightest of residue and has also been told that the ronsonol lighter fluid in the yellow plastic bottles are also impure. So SWIM was wondering if turpentine could work instead, seeing how its readily available is an organic solvent and is perfectly pure. Any thoughts would help greatly...
