- Pike Powdercoating: local powder coater; uses Prismatic Powders, have some colors in stock (i.e., Sunstorm Silver) and can get most of their 6,500+ colors in a couple of days.
- DetailPlating.com: seems focused on auto restoration market, they offer: clear zinc, Zinc Dichromate, zinc phosphate, and black zinc.

- Electroless nickel plating has several advantages versus electroplating. Free from flux-density and power supply issues, it provides an even deposit regardless of workpiece geometry, and with the proper pre-plate catalyst, can deposit on non-conductive surfaces.
To relieve the potential for Hydrogen Embrittlement in hardened steels electro-plated with Zinc, a baking procedure after the plating is required to remove, or diffuse the hydrogen throughout the basis metal, reducing the risk of embrittlement. For more information on Hydrogen Embrittlement, please read the section titled, “You Crack Me Up! Hydrogen Embrittlement is No Laughing Matter”, located elsewhere in this report. “What are the Limitations of Zinc Plating?” Zinc should not be used on critical steel parts that will reach temperatures of 500˚F, or higher, as zinc may diffuse into grain boundaries to embrittle the steel. Zinc coatings can produce bulky corrosion products during exposure to marine or tropical environments and should not be used where the products may cause binding and prevent functioning of equipment that has moving parts in contact. Rapid corrosion of zinc can occur in confined atmospheres where repeated condensation of moisture is likely and where certain organic vapors containing halogen can accumulate.
The risk for embrittlement and failure is reduced the lower the ultimate tensile strength is. In general, no hydrogen embrittlement occurs in steel below 1000 MPa or hardness below 30 Vickers. A large proportion of the hydrogen can be removed by heating.
