I'm looking for a plater, preferably in California that does black matte chrome, or black nickel matte finish.
I have a source in southern Cal. for the black chrome but they don't do it on a regular basis, ordering chemicals on an as needed basis, so it's both expensive and requires a relatively long lead time. I've used a N. Cal. shop for black nickel, but they are more a decorative plater, so asking them for .0003 of plating can be interesting.
Black oxide isn't acceptable to my customer but they are open to other dull black coatings, any ideas?
Best, Steve
