Assess and Prepare
Identify the base material and review the existing finish, corrosion and required dimensions. Remove contamination and, where necessary, old coatings to prepare a suitable surface for plating.

Military-spec olive drab finish for tools, hardware, and equipment. Corrosion-resistant and built to last in harsh conditions.
A distinctive finish for metal components
In zinc plating, olive drab refers to an olive-toned conversion coating applied after the zinc layer. This additional surface treatment gives the components their characteristic colour and helps improve the corrosion resistance of the plated finish.
A.A. Vinney’s lists olive drab among its metal finishing services in Dandenong, Melbourne. Whether you are restoring existing hardware or specifying a finish for new components, start by sharing the material, condition and appearance you need.
For replacement parts that need to sit alongside original hardware, identify which surfaces will remain visible. If your components already have paint, plating or corrosion, include close-up photos so preparation requirements can be considered.
Restoring a component or ordering a production batch requires a clear understanding of the finish. Appearance, part dimensions and intended use all need to be considered together. Discussing these details before processing helps establish whether olive drab is suitable and what result to expect. Email A.A. Vinney’s with photos, quantities and any specifications to request a quote.

Preparation, plating and surface treatment
For an olive drab finish over zinc, the process combines surface preparation, zinc plating and a conversion treatment. The sequence and any additional treatments depend on the component and its coating requirements.
Identify the base material and review the existing finish, corrosion and required dimensions. Remove contamination and, where necessary, old coatings to prepare a suitable surface for plating.
Electroplate the prepared components with zinc to form the base for the olive drab treatment. The plating requirements need to reflect the part’s intended use and any supplied specification.
Treat the zinc-plated surface in an olive drab conversion solution. The reaction forms the characteristic coloured layer and contributes to the corrosion resistance of the coating system.
Rinse and dry the components using conditions appropriate to the treatment. Check the finished appearance and coverage against the agreed requirements, with any additional sealing or testing determined by the specification.
With decades of experience across automotive restoration, industrial manufacturing, and specialist metal finishing, our team has the knowledge and expertise to deliver exceptional results on every project.

We believe in honest communication. That's why we're upfront about lead times and keep you informed throughout the process, so you always know what to expect

Every completed job undergoes a thorough final quality inspection before it is shipped or collected. If it doesn't meet our high standards, it doesn't leave our workshop.

Every job gets the same attention to detail - whether it's a single motorcycle part or a 200-piece industrial run.
Got questions before you commit? Good. Here are the ones we get asked most often.
Olive drab coating provides a muted green-brown appearance and is commonly associated with a conversion finish over zinc-plated components. The coating system helps protect the underlying metal against corrosion. Suitability depends on the component’s material, intended use and any required finish specification.
No. Olive green paint adds a pigmented paint layer, while an olive drab conversion finish chemically treats the plated surface. They differ in appearance, thickness and protective properties. If you are matching an existing component, provide a sample or finish specification so we can identify the treatment you need.
Provide a sample or clear photos so we can assess the finish you want. Olive drab can vary in shade and appearance depending on the surface condition and coating process. Discuss any colour-matching requirements before treatment, especially when several components will be fitted together.
An olive drab appearance alone does not demonstrate compliance with a military or engineering specification. If your component requires a particular standard, include the specification number, revision and documentation requirements with your enquiry so we can confirm whether the work is suitable.
Recoating may be possible after assessing the base metal, existing finish and extent of corrosion. Old coatings may need removal before the surface can be prepared and treated again. The new finish will not replace metal lost to corrosion or repair deep pitting.
Send photos, the material or grade if known, dimensions, quantity and details of any existing coating. Explain where the parts will be used and include any drawings, finish specifications or colour references. For threaded or closely fitting components, identify critical tolerances and any areas that must remain untreated.
