How do you darken filework on titanium? My preference is to let the metal show through like a bluing, but Birchwood-Casey says their blueing does not work on TI, and their Perma Fin black is a solid black. It could be airbrushed on light, but is very permanent and has to be bead blasted off, thus I can't figure out how to put it on only in the file cuts. OR do others NOT "enhance" the filework?
Thanks
