Hi and thanks for all the info. I have done i bit of search about a month worth on identifying the pure Turpentine and getting hold of it and it is not clear cut for lots of misleading and contradictory info on the web. But. I did buy some in Canada (no shipping of this stuff from US) and apparently found a source. Just to make darn sure I got the true turpentine, I did some more searching and found this.
A gallon or two of true Pure gum spirits of Turpentine. Nothing else will do. Not Spirits of Turpentine. Not Turps. Not Turpentine. And, even if it says on the can that it is Pure gum spirits of turpentine, don't believe it. Smell the stuff. If it doesn't smell exactly like pine sap, don't use it--it probably has some petroleum additives to increase its bulk. And even if the store keeper says that nothing is added, trust only your nose. If it don't smell like pine sap, it probably isn't.
