Wheel Refurbishment: Hidden Truths & Expert Tips

Introduction

Alloy wheels are a major part of a car’s visual appeal and performance, but they take a beating from kerbs, potholes, and the elements. Wheel refurbishment seems like an easy fix, but not all refurbishments are created equal. There’s a lot more to it than just making your wheels look shiny again! Before you book a refurbishment, here are the hidden truths you need to know.

1. Powder Coating Can Weaken Wheels (If Done Wrong)

Powder coating is a durable, long-lasting way to restore alloy wheels. However, excessive heat during the curing process (above 180°C–200°C) can alter the metal’s structure, making the wheel more brittle. This is particularly risky for high-performance wheels, where strength is critical.

Solution: Opt for refurbishers who use low-temperature curing powders or alternative finishes that preserve the wheel’s integrity.

2. Diamond-Cut Wheels Have a Limited Lifespan

Diamond-cut alloy wheels are CNC-machined to achieve a striking polished finish, but every time they’re refurbished, a thin layer of metal is shaved off. After 2-3 refurbishments, the wheel becomes too thin and structurally weak.

Alternative: A high-gloss polished finish mimics the diamond-cut look without the risk of thinning your wheels down to dangerous levels.

3. Not All Cracks Should Be Repaired

Cracked wheels can often be welded, but some repairs are downright dangerous. If a crack is near a spoke or has already been welded before, it can compromise the wheel’s structural integrity, leading to potential failure at high speeds.

Rule of thumb:

  • Small cracks on the inner barrel = Safe to weld.
  • Cracks near spokes or bolt holes = Replace the wheel.

4. Mobile Repairs: Convenience vs. Quality

Mobile wheel refurbishment services offer convenience, but they often fall short in terms of durability and thoroughness. While they can be useful for minor cosmetic damage, they typically don't provide a full, long-lasting repair.

Potential Risks of Mobile Repairs:

  • Lack of Proper Stripping – Many mobile refurbishers don’t strip the wheel down completely, leading to old damage reappearing over time.
  • Limited Curing Process – Without industrial ovens, mobile refurbishers often rely on air-drying methods that aren’t as durable as powder coating.
  • No Structural Repairs – Mobile services typically only deal with surface-level issues; cracks, buckles, and corrosion remain unaddressed.
  • Hidden Costs – A quick fix might seem cheaper upfront, but if the finish fails within months, you may end up paying for a full refurb later.

Best for: Minor kerb scuffs and touch-ups.

Not recommended for: Deep scratches, corrosion, structural damage, or high-end alloy wheels.

5. Cheap Repairs Could Lead to Air Leaks

If the bead seat (where the tyre meets the wheel) isn’t treated properly, it can cause slow leaks. Some budget refurbishers skip this step, leading to ongoing tyre pressure issues.

Solution: Always ask if the bead seat will be cleaned and prepped properly before refinishing.

6. Colour Matters More Than You Think

  • ✔ Darker wheels hide brake dust better.
  • ❌ But they show kerb damage more clearly.
  • ✔ Silver wheels resell better because they’re OEM-standard.
  • ❌ Unusual colours (gold, bronze, bright red) may reduce resale value.

Best balance? Shadow chrome or anthracite grey – modern, stylish, and practical.

7. Diamond-Cut Lacquer Fails Faster Than You’d Expect

  • Stone chips allowing moisture in, causing corrosion.
  • Harsh weather conditions speeding up deterioration.
  • Poor refurb jobs using weak lacquer.

Prevent this by: Applying ceramic coating over the lacquer for extra protection.

8. Some Wheel Welds Can Be More Dangerous Than the Original Crack

A poorly done weld on a cracked wheel can be worse than the crack itself, leading to a weak spot that might fail under stress. Always ensure:

  • ✔ The weld is done by a professional using the right alloy.
  • ✔ The wheel is X-ray or dye tested to ensure full penetration of the weld.

9. Powder Coating vs. Wet Painting – Which Is Best?

Feature Powder Coating Wet Painting
Durability ✅ Strongest & most resistant ❌ Less durable
Colour Options ❌ Limited ✅ More OEM-matching options
Finish Quality ✅ Smooth & even ✅ Factory-perfect look
Repairability ❌ Hard to touch up ✅ Easy to fix chips

Verdict: Powder coating is best for durability, while wet painting is better for factory colour-matching and minor repairs.

Final Thoughts: Should You Refurbish or Replace?

  • ✔ If your wheels are rare, high-performance, or OEM – refurbishment is worth it.
  • ✔ If the damage is mostly cosmetic – go for a high-quality refurb.
  • ❌ If the wheel has major structural issues – replacing is the safer option.
