The screws are Ti. Yes, this is an empty shell. All the rest of these are assembled to the point of just needing the little black magic converter and away they would go... At this point, this special LunaSol of color may get out of the shop along with the plain flavored others.
At one point, I wanted to shoot a short video of dunking a fully functioning Ti PD or sister light in the anodize bath and show it getting colored while on. The point of this would be to show that all exposed metal is Ti and that which isn't, is safe behind seals. I don't have a video camera so it never happened. I have one phone that can shoot video but it is hardly worth the effort and you need to catch the action the first time..... Besides, such an exercise would reek of marketing hype I think. One might respond with "So what?"
In the past, I have received "all titanium" items and when subjected to the anodize bath it became obvious that some parts were not Ti. :green: Any other metal immediately sets off to bubbling like crazy in the bath and it can impede the Ti from even starting to oxidize (color) as the electrical path is focused on the other metal.
