Restore That Factory-Fresh Finish with the Right Process
Diamond cut alloy wheels are known for their sharp, reflective finish and stylish two-tone design — but they’re also notoriously prone to damage. Kerb scuffs, corrosion, and general wear can take the shine off quickly. So, how do you repair diamond cut alloy wheels properly?
At Alloy Xpress, we specialise in professional diamond cut refurbishments — here’s a behind-the-scenes look at how it’s done, and what to expect if you’re thinking of getting yours restored.
What Makes Diamond Cut Wheels Different?
Before diving into the repair process, it’s worth understanding what makes diamond cut wheels unique. Unlike standard painted alloys, these wheels have a precision-machined face, achieved by using a lathe to skim off a fine layer of metal. This gives that mirror-like shine and crisp, clean lines.
However, because the finish is exposed metal (protected only by lacquer), it’s more vulnerable to corrosion, stone chips, and kerbing.
Can Diamond Cut Wheels Be Repaired?
Yes — but it takes the right tools and expertise. Diamond cut wheels require specialist equipment to achieve a factory-quality finish. A simple DIY fix or touch-up won’t cut it (literally).
Here’s how the professionals do it.
Step-by-Step: How Diamond Cut Wheels Are Repaired
1. Inspection & Preparation
First, we assess the wheel’s condition. If there’s structural damage (like cracks or flat spots), we’ll advise on repairs or replacements. If it’s cosmetic, we’re good to go.
The tyre is removed, and the wheel is chemically stripped to remove old paint, lacquer, and grime.
2. Damage Removal & Surface Prep
Kerb damage and corrosion are addressed by sanding and smoothing the surface. The goal is to create a clean, even base before refinishing.
3. Powder Coating or Priming
If the wheel has coloured inserts or accents, we apply a powder coat or wet paint base first. This is cured in an oven to ensure durability.
4. Diamond Cutting
Using a CNC lathe, we precisely skim the face of the wheel to reveal fresh, shiny metal. This process is ultra-precise — just microns are removed at a time. The result is a crisp, high-gloss finish with perfect lines.
5. Clear Lacquer Application
To protect the exposed metal from corrosion and daily wear, a tough clear lacquer is applied. This seals the finish and restores that factory-fresh look.
6. Final Curing & Quality Check
The wheel is baked in a curing oven, then reassembled and balanced. We carry out a final quality check to ensure everything is spot on before handing it back.
How Many Times Can a Wheel Be Diamond Cut?
Each time the face is cut, a small layer of metal is removed. While this doesn’t affect performance initially, there is a limit — most wheels can only be diamond cut 2 to 3 times safely, depending on the manufacturer’s specs and original thickness.
If a wheel has already been cut multiple times, we may recommend switching to a full powder coat for longevity and strength.
DIY or Leave It to the Pros?
Diamond cut repair is not a job for a mobile van or home garage setup. It requires a CNC lathe, curing ovens, and trained technicians. Attempting a DIY fix could make things worse — or permanently ruin the wheel.
At Alloy Xpress, we use industry-leading equipment and experienced staff to get your wheels looking brand new again — safely and professionally.
