John - In a nut shell NO. I have looked in to a lot of EP systems for Titanium and all of them employ some nasties. Weather Chrome, flouride, or varieties that tend to be explosive. The trick is that titanium metal is rather reactive. The surface oxide is rather unreactive. The nasties are required to remove the surface oxide. I have played with some and have had results from dismal to unbelievable. Either case none I have found would I put into a production environment.
