I'll try polishing, thanks.
AFA trying it - it's not trivial, but go for it!
Lucky for me, we do R&D on machining Ti, so I'll grab some from the scrap pile.
I meant to type, "NOT worth what he charges." I will give it a go, I just like to work out all the details before I jump. Handy on the titanium scrap, every place I've visited that machines titanium controls scrap pretty closely. I bought a variable DC power supply which, hopefully, will remove at least some guesswork. Did you start with battery acid before dilution, or a higher concentration? My plan is to use lye to de-smut, dealing with one type of acid bath is enough.
