I have been using actual Slackum finish from England for years Then I was using Trade secret now my supply has run out and I can't get the Trade Secret any longer. I have mixed up the recipes posted by others that are the "London oil finish" but they do not set up like the slackum or trade secret did, where they got very tacky and that was when I rubbed in the talc as I rubbed off the oil. The recipes I followed just seem to dry without getting that gummy sticky consistency. Is there something I am missing?
