Re: Chrome, gold plating, brush plating, vapor deposition

The info I gathered was that the vapor deposited aluminum gas chamber coatings were very thin and needed to be overcoated for protection and corrosion resistance. If used outdoors tarnishing would occure. The gold on the V being uncoated would have done intentionally to let light through.
I did see people on the net plating at home and the corrosive acids and gasses would seem to make this impractical. The brush plating was interesting and using 5-6 volts DC to plate seemed like a great solution for some items. Seems their process of coating with an adhesion layer and then a conductive paint on layer eliminated alot of the caustics but coating on the OUTSIDE of plastic would not be acceptable in this lens application. Anyone used/ using the brush plate kit?
