David,
Turps (my slang for conventional turpentine) and Venice turpentine are two different compounds. Venice turpentine is commonly used to condition horses' hooves and is much thicker. As an aside, I've tried the Venice turpentine substitutes but it is not nearly as effective as the real stuff. E-mail me your address and I'll send you some. Cobalt drier is another drier that is avaialble at Joann's or artist supply stores. I've not used it. Read and try different mixtures to see what works best for you. Have fun!
