Brake Booster Plating

When plating a booster you can do 100 boosters one after the other and get many different finishes, the metal helps determine how light and dark the final outcome will be. There is no exact science to it.

It has been my experiance (@ a US Naval Shipyard Plating plant) that the tint-coloration (Gold-Green-Yellow-Brown) tinting is determined by the duration of DiChromate treatment after the primary electroplating coating is applied, be it zinc, cad, etc,,,
The surface condition can effect the level of 'Gloss' for lack of a better term (i.e. Brightness) Blasting parts prior to plating is usually not desired. It can be difficult to find local plate shops who even runs traditional cad tanks due to tightend eco rules (cyanide issues). It is amazing how much is plated on the cars when you really examine all the parts and you can save a ton ($$)on replacment costs if you can find a resonable priced plater to work with.
