Have you ever wondered why alloy wheel specialists recommends a powder coat process for repairing and refurbishing alloy wheels?
Diamond Alloys is a
powder coat specialist and to help you answer this question we have put together a list of the benefits of applying a powder coat process to your alloys along with some common questions with their answers.
The Benefits of Powder Coating Alloy Wheels
- You’ll achieve a better and more durable finish with a powder coat.
- Achieves a longer lasting result compared to painting alone.
- Typically a one coat finish it can offer a quicker turnaround for completion.
- Powder coating is an environmentally safe process because it produces few volatile organic compounds (or VOCs).
- Creates the most even finished surface (horizontal and vertical) because the powder is sprayed and heated without drips or application traces.
Most Commonly asked Question About Powder Coating?
What colour finish can I achieve with a powder coat?
There is a wide range of colours available. You can also add texture, achieve a matt or gloss finish.
Is a powder coat finish dangerous?
Powder coating are not classified as dangerous and there are no solvents used in powder coating.
Does powder coating prevent rust?
Unfortunately no, but the finish is durable and last longer than many other processes which is why it is so possible, ensuring return visits to the workshop are fewer.
Can I get powder coated alloys diamond cut?
Yes, all our
Diamond Cut allows wheels have a powder coat base. This can be painted a colour to accentuate the effect of the cut.
Can I get a smart repair powder coat?
No. Powder coatings are a workshop applied using specialised equipment. The equipment includes an electrostatic spray gun, spray booth and an oven to bake the coating. On site application is not possible given the hot curing cycle required to fuse the coating.
What has static electricity got to do with powder coating?
Powder coatings are electrostatically charged by the spray gun. This works by very high voltage (80,000 to 100,000 volts) being delivered to the electrode. This high voltage ionizes the air creating a field of electrons or negative charge. The powder is pneumatically conveyed into this electrostatic field, picks up a charge then heads to the nearest ground. So lots of static electricity is generated by the spray system.
How should I care for my powder coated alloys?
Pollution, dirt, grime and salt can all accumulate on a powder coated surface over time. To extend the life of your powder coated alloy wheels a simple regular maintenance program should be implemented for the removal of residues.
In areas where pollutants are more likely, especially in coastal or industrial regions, a cleaning program should be carried out on a more frequent basis. To clean a powder coated surface, carefully remove any loose deposits with a wet sponge and then use a soft non-abrasive brush or cloth in combination with a mild household detergent solution to remove dust, salt and other residues. Finally rinse all powder coated surfaces with clean water.
Alloy wheels have been offered sporadically since 1924. Before this, wheels were usually comprised of two pieces of pressed steel – the rim and the disc – which were welded together. The other option was an aluminium rim, which was connected to the centre by metal spokes.
One of the first to realise that alloy wheels have the power to offer greater stiffness and reduced weight was Ettore Bugatti, who featured them on his Type 35 in 1924. The wheels also improved brake cooling, and Bugatti continued to develop cast alloy wheels until he arrived at the stunning 24 inch version used on the Type 41 Royale.
After the Second World War, the alloy designs were augmented by Panhard, which developed a radially finned aluminium brake drum to double as the wheel centre. Cadillac and Pontiac later introduced similar versions, which also had a centre cap covering the mounting lugs. Many vehicles had an adapted plate that allowed for the open-centre rims to work with wheel balancing machines.
The 60s saw more makes offering alloys, although they still weren’t hugely popular. Abarth put magnesium wheels on most of their models from 1962, while Ferrari introduced their first alloy, the magnesium Cromodora Starburst, on their 275 GTB in 1964. The Corvette, the Alfa Romeo GTA, the 1965 Mustang, the 1965 Lamborghini Miura and the 1966 Fiat Dino also featured alloy wheels. Porsche came to the party slightly later, adding their first alloy to the Porsche 911S in 1966. They were consistent, however, and the alloy has remained standard on the 911 for decades. Aston Martin came to the party with an alloy on the DBS V8 in 1969, with Mercedes following a year later.
A variety of different wheels were favoured by different manufacturers, but it’s estimated that the Minilight wheel, introduced in 1964, was the most popular aftermarket wheel ever. Available in both magnesium and aluminium, the wheels were used by factory competition teams everywhere. The first budget-friendly wheel available to all motorists was an aluminium alloy offered on the VW Golf, Scirroco, Passat and Audi in 1974.
Alloy wheels finally reached peak popularity in the 1980s, and have remained that way ever since. Although their styling and design has evolved over the years, the benefits remain: better stiffness, lighter weight and unique styling that puts your own individual stamp on your car.

According to Oliver Rak, Project Manager at Mercedes Benz, when it comes to what is on trend for alloy wheels this year “It is a continuation of last year's trends: large formats are still very much 'in', as well as are light-alloy wheels with a high-sheen finish, whose allure stems from the contrast between the seemingly bare metal surface and the painted areas.”

Have you ever had someone ‘pop in’ to see you unexpectedly? Did you then do what millions of us do, and spend five minutes frantically making the place look as clean and tidy as possible – perhaps by hiding all the dirty dishes in a cupboard? There’s no shame in these temporary measures, because that’s just what they are – temporary. You’re simply trying to give your guest a pleasant experience, not to mention protect your reputation as a homeowner! What you're not doing is permanently keeping those dirty plates in the cupboard, or leaving that pile of un-ironed laundry hidden behind the sofa forever. That would be terrible, right?
If you agree with that, then you can imagine how we feel about companies that only repair and maintain the front of the wheel. It’s the same kind of thing – they’re only treating the areas that people can see and letting the hidden areas, in this case the back of the alloy, become filthy and unloved. The worst thing is that it often isn’t made clear that this is what the company has done, mean that customers think that their wheels are more protected than they are in reality.
Here at Diamond Alloys we powder coat and paint the entire alloy, not just the front. This is because we are committed to providing the highest quality service possible, and because we believe that all parts of an alloy should be cared for equally, regardless of whether or not they are visible.

One of the questions we get asked a lot is ‘what colour should my alloy wheels be?’ This is often because people see car manufacturers introducing models with particular colours of alloy, particularly for higher end cars, and assume that there is a right way and a wrong way to style their car.
