Coating The Two Surfaces Everyone Forgets

Wheels: the hottest surface on the car

Brake dust is not dust in the ordinary sense. It is hot ferrous particles thrown off the pad and rotor at temperature, and when it lands on a wheel face it can partially embed into the finish. That is why a neglected wheel goes from dirty to permanently stained, and why a stiff brush and a strong cleaner eventually dull the finish trying to shift it.

A wheel coating is a high-temperature-tolerant version of the same chemistry used on paint. It gives the dust a hard, slick surface to land on instead, so it sits there until you rinse it rather than keying in. In practice that means a wheel you clean with shampoo and a soft brush instead of an acidic wheel cleaner, which is better for the wheel and better for you.

Melbourne wheels cop a specific version of this. Stop-start traffic on the Eastern Freeway and the Monash generates a lot of pad wear, and cars in the bayside suburbs like Brighton get salt aerosol settling into the same barrels, which accelerates corrosion where the finish is already compromised by kerb rash.

What we do to wheels

Wheels come off. Each is cleaned inside and out, decontaminated with an iron remover, tar-solvented where needed, dried and panel-wiped. Faces get inspected for kerb damage — we will tell you if a repair is worth doing first rather than sealing over it. Then the coating is applied to the face, the spokes, the barrel and usually the inside lip.

Calipers can be coated at the same time while the wheels are off, which is worth doing on painted calipers that have started to go chalky.

Glass: it changes how you drive in the rain

A hydrophobic glass coating makes rain bead and, above roughly 60km/h, clear the windscreen on its own airflow with the wipers off. In Melbourne that is genuinely useful, because the cool-change squalls that come through here are short, heavy and often arrive at the worst part of a freeway run. Less wiper use also means less abrasion on the screen and less judder.

It is not magic below highway speed — sitting in traffic on Hoddle Street in heavy rain, you still need wipers. The other honest limitation is lifespan: the windscreen is the shortest-lived coated surface on the car because the blades are actively wearing it.

Side and rear glass is where it pays off quietly. Clearer mirrors and side windows on a wet night on the Princes Freeway heading out towards Werribee is a real safety difference, and those surfaces hold the coating for years.

Booking it

Wheels and glass are usually added to an exterior coating job because the car is already stripped and decontaminated, which keeps the labour down. They can also be done on their own.
