Plating for power brake booster tube and fitting

[Maxsg1973]

When you guys restore your power brake booster tubes and fittings what finish did you use? I blasted and zinc plated mine with my Caswell kit. I decided not to do the chromate conversion coating because I thought it looked correct. Only draw back is it has no protection and the typical zinc white rust is setting in. The haze you see on the bracket is the white rust and it polishes away very easy. What is considered the correct finish? Please take a look at the pic below and give me your opinion. Any and all feed back is greatly appreciated.

TYPE II Chromated with color (yellow, gold, black, or olivedrab)
TYPE III Clear (Blue) chromate

Are you Post treating using: BLUE CHROMATE CONCENTRATE - 8OZ  Caswell SKU # BCC8

I did not do the chromate conversion. I do have the clear/blue chromate concentrate. I thought it would make it look to shinny like my alternator fan. I was under the impression it should be more dull like cadmium plating so that why I choose not to do the blue chromate. I figured with the white zinc rust it would look more correct after it aged but I'm second guessing my decision.  Should it be more of a bright zinc like my alt fan or a dull cadmium? I can make it just like my alt fan if that is correct.
