Restoration / Re: Power Brake Booster Valve: A Comparison between Original vs Reproduction
« on: November 02, 2016, 11:48:38 AM »
Digging this thread up again as there was a recent discussion about check valves, and I realised I hadn't updated this with my experiment to impart some 'aged color' to the very white reproduction that Bentley originally posted pics of.
So - this is the comparison. The valve on the right was the result of soaking in a zip-lok bag containing a strong coffee. I started off leaving it for 24 hours, but it barely took on any of the color; this picture is after about a week in the bag. The artificial lighting makes it contrast heavily against the as-purchased repro on the left, and appear maybe a little too dark, but in natural light it looked very much like an original on a friend's car.
Still lacking the patina of a used original, but when installed, far less obvious as a repro to me. In hindsight, I would have removed it a day or two sooner, but being honest I got sidetracked and forgot it![Roll Eyes ::)](http://www.camaros.org/forum/Smileys/default/rolleyes.gif)
Interested in opinions!
