Hazing

A hazy effect on your paintwork can be caused by chemical burns from strong detergents, but is more likely the result of oxidation. In severe cases, this will make the paintwork flat or matte.

In years past, the effects of oxidation were far more obvious as it would break down the binders in the paint, causing it to look matte and powdery. You may well have seen old post office vans where the paintwork has turned pink, and you might even see what look like white patches of dust. This was why T-Cut was such a popular product, as it would cut away all this dead paint.

On modern cars the effect is far less obvious and may only be a very slight hazing to the surface of the paint. It really is just the very uppermost layer of the clear coat which is effected so is very easy to remove with a light polish, it can even be done by hand.

What it means

Hazing is the cloudy, slightly milky look you sometimes see in paint after it has been polished or compounded. Instead of a crisp, clear reflection, the surface looks soft and smeary, as if there is a light fog over it. This is usually caused by very fine scratches and micro-marring in the clearcoat, often left behind by an aggressive pad and compound, dirty pads, or simply stopping at too coarse a stage and not finishing the paint properly.

Why it matters

Gloss is the casualty. Even where the deeper defects have gone, hazing robs a finish of sharpness and depth, so the paint never quite looks right however much work has gone into it.

It also gives away how the job was done, because haze and micro-marring are classic signs of heavy cutting that was never followed by proper refinement with finer pads and polishes. Awkwardly, it hides in ordinary light, showing up under strong sun, forecourt lamps or inspection lighting, so a car can look fine in the shade and disappoint the moment it is out in the open.

Timing matters most before protection goes on. Ceramic coatings and sealants seal in whatever is underneath them, so haze left in the clearcoat becomes a cloudy finish locked under the coating.

Which lighting reveals it

You will see hazing mentioned on detailing and paint correction estimates, inspection reports and training material. Technicians may talk about compound haze, DA haze, rotary haze or micro-marring when describing the dullness left after the cutting stage. It is most obvious on dark colours, especially black and deep blue, where any loss of clarity stands out.

Context

Hazing sits in the same family as swirl marks and holograms, but is more about general cloudiness than distinct swirl patterns. It often appears after heavy machine compounding, dry polishing, using very aggressive pads or allowing pads to clog up with used compound and removed paint. The usual cure is an additional refinement stage using a softer pad and finer finishing polish, sometimes preceded by a lighter re-cut if the original compounding marks are too deep. Dark colours, especially black: are where it shows most unforgivingly. In the workshop, we plan at least two stages on any serious correction job: the cut removes the defects; the refinement stage removes what the cutter left behind.

Common mistakes

• Stopping after a heavy cutting stage and assuming the job is done, leaving compound haze across the whole car.
• Using very aggressive pads and compounds on soft paint without planning enough refinement stages to clear the haze they create.
• Working with dirty or clogged pads that scour the surface and add fresh micro-marring while trying to remove older defects.
• Applying wax, sealant or ceramic coating straight over hazy paint, then blaming the protection product for the lack of clarity instead of the underlying finish.
