Before and After Wheel Repair: How to Judge a Rim Restoration

Before-and-after photos are the standard proof in this trade, and they are also easy to stage. A flattering angle and warm light hide a repair that will lift within a year. Here is how to judge one properly — including ours.

Why before-and-after shots can mislead

Almost any repair looks good in a close-up taken at the right angle. The things that separate a lasting repair from a cosmetic one are visible only from specific viewpoints, and a photographer choosing the shot controls exactly that.

None of this means photos are worthless — ours are real customer wheels, and you should expect to see a shop's work. It means you should know what to look for rather than accept the picture at face value.

The four checks, in order

1. Sight along the lip, not at it

Crouch and look down the edge of the wheel so the rim runs away from you. The repaired section should follow the same curve as the rest with no flat spot, no dip and no bulge. This is the check that catches filler packed into a gouge rather than the profile being rebuilt — filled repairs read as slightly flat along the edge, and a straight-on photo never shows it.

2. Change the light

Move the car from shade into direct sun, or walk around it. A colour match that is close but not right reveals itself the moment the light changes — a silver that is a shade too warm looks perfect in the shade and obviously wrong in sunlight. Judge at about two metres, which is how people actually see your car.

3. Look for a hard edge

A properly blended repair has no boundary. If you can find the line where the new finish stops and the original begins, it was not blended — it was masked and sprayed. That edge is also where the finish will start lifting.

4. Check the grain on a machined face

If the wheel is diamond-cut, the fine concentric lines must run continuously across the repaired area. If that section is smooth, or hand-painted to imitate the grain, it will read as a repair from three metres in any light — and it means the face was not re-cut on a lathe.

A correct repair is not one you cannot find in a photograph. It is one you cannot find standing next to the car.

What "after" should not look like

• Overspray on the tyre. A fine grey mist on the sidewall next to the rim means the wheel was sprayed on the car, not properly masked or removed.
• A glossier patch. If the repaired area is shinier than the rest, the clear coat was laid on locally rather than blended.
• Texture underneath. Run a fingertip across the repair. Grit trapped under the finish means the surface was not clean when it was sprayed, and it will fail early.
• A wheel that looks new while its three siblings look used. Matching is the job on a single-wheel repair. A repair that stands out because it is too good has not been matched.

Ask what was actually done

A shop that did the work properly can describe it without hesitating. Reasonable questions:

• Was the damaged material removed or filled? Cutting back to clean metal is what makes a repair last — see how curb rash repair actually works.
• Was the wheel checked for runout? A kerb strike hard enough to tear metal can also bend the rim, and a cosmetic repair over a bent wheel leaves you with the vibration.
• What finish was used, and why? The answer should reference your wheel specifically, not a generic process.

Judging the price against the result

A cheap repair that peels in eight months costs more than a correct one, because the second shop has to remove the first shop's work before it can start. What legitimately moves the price is finish type, damage depth and quantity — set out in what drives alloy wheel repair cost.
