Where can I buy sulphuric acid?
Thanks for your replies. I'll try the drain cleaner approach.
The closest anodising firm to me is about 15 miles away, and the one
time I did go to them they made a mess of one of my parts, and lost
another, so I'm not going back there. And yes, titanium may be easier
to anodise, but not to machine in the first place!
thanks,
dan.
