I am trying to use an 8+ year old tube of the Tormek PA-70 honing paste but it is too thick. It is “squishy” in the tube but comes out lik ultra thick caulk like a very soft eraser and cannot be spread onto the leather wheel. I have ordered more of it but it will arrive next week. Is there anything such as light oil that I can mix into it to make it work before my new tube arrives?
