Diamond cut alloy wheels look stunning when new. That shiny, two-tone finish gives your car a clean, polished look that turns heads. But here’s the downside, diamond cut alloy wheels are more delicate than they look. Even light scuffs, kerb damage, or brake dust can dull their mirror like finish in no time.
Unlike standard alloys, these wheels are cut with a fine diamond tipped lathe to create that crisp shine. That means the tiniest mark can break the surface, allowing corrosion to sneak in. If your wheels are starting to look cloudy or scratched, it’s not just a cosmetic issue – it’s a signal that they need a diamond cut alloy wheel repair before things get worse.
Key Takeaways for Diamond Cut Alloy Wheel Repair
-
Diamond cut alloy wheels offer a premium, mirror-like finish but are more prone to damage and corrosion than standard alloys.
-
DIY fixes often fail to restore the factory shine and may worsen damage; professional CNC repair is the safest option.
-
The diamond cut repair process involves precision steps like laser scanning, lathe cutting, and powder coating to restore both appearance and integrity.
-
Refurbishing costs (£60–£400) are significantly lower than replacing wheels (£300–£500 each), preserving both style and resale value.
-
Proper aftercare—using pH-neutral cleaners, sealants, and avoiding kerbs—extends the life of refurbished wheels.
Can DIY Fixes Match a Factory-Fresh Shine?
Numerous online videos claim to show you how to repair diamond cut alloys at home. But let’s be honest: these wheels are not made for home repairs. A simple sanding kit or inexpensive polish won’t restore the sharp reflections that diamond cut wheels are known for.
Trying to fix them yourself might cause more damage. That precision-cut layer is extremely thin. One wrong move, and you could grind away too much metal, making the wheel unrepairable. That’s why professional diamond cut alloy wheel repair services are always the safer choice if you care about quality and value.
What Makes Diamond-cut Repair Different from Regular Alloy Refurbs?
Unlike standard alloy wheel refurb methods, diamond cut refurbishment utilises CNC machines (Computer Numerical Control systems) that remove a super-thin layer from the wheel’s face. This removal exposes a fresh layer of clean metal, restoring that signature shine.
The process is far more advanced than powder coating or spray painting. Alloy wheels diamond cut require precision to maintain their unique look, especially if your wheels have a two-tone design. Without the CNC machine and expert control, you’ll never get that factory finish again.
The Precision CNC Process—A Quick Walk-Through Steps
So, how do the professionals handle diamond cut alloy wheel repair? It’s a five-step process designed to restore both looks and structure:
1. Inspection & Prep
This is the first step of the process, where the wheels are sent straight onto a balancer. They are then checked for cracks, buckles, and previous repairs. If the rim is more than 2 mm out of round, it’s unsafe to cut again.
2. Stripping & Cleaning
In the second step, the old lacquer dissolves in a gentle chemical bath—no harsh acids that pit metal. Then comes pressure washing residues and bead blasting stubborn paint in vents. The bare aluminium must be spotless; any grit will score the next cut.
3. CNC Lathe Mapping
The rim is then mounted on a precision hub adapter and scanned using a laser probe to inspect the face. The software builds a 3-D model, calculating exactly where to skim 0.25 mm, just enough to erase the rash without weakening the wheel.
4. Diamond
A V-profile diamond tip glides across the spokes at 1,200 RPM, leaving microscopic ridges that catch light like a CD. The coolant maintains a temperature below 50 °C to prevent warping. The machine pauses between passes to verify depth; most wheels can only be cut twice in their lifetime before there’s not enough metal left.
5. Powder Coat or High-Gloss Lacquer
All aluminium dust is blown off, and then the wheel is flash-heated. A clear powder coat melts at 180 °C, flowing into every ridge, sealing out water and salt. Two-tone wheels get colour-baked first, diamond-cut second, and then clear-coated.
6. Curing & Final QC
Lastly, the wheels are baked in a convection oven to harden the finish. Once cool, run-out is measured again, and the lip is hand-polished. Any wheel failing a 0.1 mm tolerance goes back for rework.
Loco’s Customs’ diamond cut alloy wheel repair method ensures the wheel’s surface remains true to its original look while providing it with the protection it needs for long-term use.
Safety & Warranty: How Diamond Cut Alloy Wheel Repair Protects Both Style and Value
There’s more to diamond cut wheels refurbishment than meets the eye. Safety matters, too. Damaged wheels can affect your car’s balance, tyre wear, and even braking.
By choosing a trusted service provider like Loco’s Customs, you’re not just getting a shiny wheel; you’re investing in a repair that’s backed by quality control and (often) a 12-month warranty. That’s peace of mind. Most home fixes or mobile repair vans just can’t give.
Cost vs. Replacement: Why Diamond Cut Alloy Wheel Repair Saves Money and Resale Value?
The alloy wheel refurbishment cost is typically much lower than replacing the entire wheel. Depending on the size and damage, refurbishing a diamond-cut alloy can cost between £60 and £400.
Compare that to buying a new OEM wheel, which costs £300–£500 each. That’s a massive saving, especially if you’ve got a full set. Additionally, properly restored diamond cut alloy wheels can enhance your car’s resale value and make it easier to sell.
Keep the Shine: Easy After-Care Tips to Make Your Wheels Last
Once your diamond cut alloy wheels look brand new again, you’ll want to keep them that way. Here’s how:
- Clean regularly using pH-neutral wheel cleaner (no acid-based products).
- Avoid automatic car washes—they use harsh brushes that can scratch the lacquer.
- Use wheel sealant every few months to add a protective layer.
- Avoid kerbs and potholes (easier said than done, we know).
- Dry your wheels after every wash to stop water spots and corrosion.
With proper care, your refurbished wheels can last just as long as new ones—without the cost of a full replacement.

Frequently Asked Questions
What are diamond cut alloy wheels?
Diamond cut alloy wheels are a type of alloy wheels that use machines with a tiny, diamond-tipped blade to scrape off a paper-thin layer from the face of the rim. This scraping leaves the metal super smooth and mirror-shiny. The rest of the wheel retains its paint or powder coat, resulting in a cool two-tone look: bright metal on top and a colour underneath—that screams “premium.”
How much does repairing diamond cut alloys cost?
On average, Diamond cut alloy wheel repair can cost anywhere between £60 and £400 in the UK. At Loco’s Customs, you can request a free-of-cost estimate. It depends on your car’s brand, make, and model.
How to remove scratches from diamond cut alloy wheels?
You can remove light scratches from diamond cut alloy wheels by polishing if they’re only on the lacquer. Deeper scratches require professional repair, which can be achieved using a CNC lathe to recut the surface. DIY sanding is risky and may cause permanent damage to the wheel.
What is the difference between alloy wheels and diamond cut alloy wheels?
Alloy wheels are made from a mix of metals (usually aluminium) and can be finished with paint or powder coating. Diamond cut alloy wheels are a type of alloy wheel featuring a shiny, two-tone finish, created by machining a thin layer off the surface using a diamond-tipped lathe. The primary difference lies in the cutting process and the glossy, high-end appearance of diamond-cut alloys.
