Title: Hard chrome - convertible windshield molding header trim
Post by: nvr-enuf on September 12, 2020, 11:42:06 AM
My 68 convert header piece needs to be redone and I believe it is “hard chrome” not shiny chrome

Does any forum members have a contact for redoing this piece ?


Pls reply or pm me
Thanks
Scott

I have not heard referred to as hard chrome but regardless Tim Lea told me he had someone at one time that did some.

I had a company(now defunct) re-chrome my 69 header and visor pieces and it was really hard to get the satin look of it. They told me they had to trying it multiple times to get the look. Gary

It’s called satin chrome. The original process was done by shooting high pressure water onto the chrome shortly after the move from the vat. Nobody has that exact technique anymore except in industrial applications but there are companies that can simulate a look

I have minimal experience with automotive decorative chrome, but design and build custom machine tools with industrial chrome.  Hard chrome is typically applied to worn or under size surfaces to restore size.  Always need to be ground back to a specific, finish size.  Seldom practical to apply over .015 inch.

We use satin chrome on handles, levers and knobs to prevent corrosion and improve appearance.  Same as seen on Starrett micrometer frames and machinist's pocket scales.  Essentially the same electrolytic processes as hard chrome.  But surfaces are first vapor blasted with a micro abrasive to achieve a uniform, mat finish.  Chrome application is no more than .0001-.0002 inch.  Has become increasingly expensive.
