Plating for power brake booster tube and fitting

[Edgemontvillage]

Although I haven't restored the specific power brake booster tubes and fittings you are asking about, we routinely use a blue chromate conversion coating following clear zinc plating on most any part we clear zinc plate. We use Caswell products too and find blue chromate produces a finish that is closer to what's available from commercial platers (clear zinc) and it serves to prevent zinc oxidation. Hope that helps.

Thank you Lloyd. I'm going to go with blue chromate conversion. I can always change it later if needed. I'm probably will have to plate it again but I'll try dipping it in the blue chromate and see what happens. I feel like a mad scientist when using this stuff.

Good to know you use the Caswell kit and blue chromate conversion coating on other parts. Helps to know how our fellow hobbyists are finding creative ways to simulate the original finishes. Thanks again.
