Does anyone know of a good surface finish - other than paint or chrome -
that can be applied to steel nuts, bolts, screws, etc. (probably even to TD
carburetor overflow-pipe clips)? I'm thinking of something like the black
oxide coating found on hardened cap screws, for example. Ideally it would
be a process suitable for application in the home garage, but even advice
about a good commercial process would be welcome.
What I looking for is a way to protect the unique fasteners on my TC engine
that would create a more-or-less original appearance without having to
replace the generally expensive little things. The throttle adjusting
screws are a good example. Chrome looks out of place, as does paint, which
also messes up the threads, but leaving them unfinished has invited rapid
rusting. What do others do?
