Ceramic coating in Greenacre

A ceramic coating is clear, and it hardens over whatever the paint looks like on the day. Put it over swirls and the swirls stay, locked under a layer that lasts years. That is the most common failure in coating work and the reason a cheap coating quote is cheap: the preparation has been left out.

So the sequence does not change. Assess the paint and take depth readings. Decontaminate chemically for iron and tar, then clay. Correct. Panel-wipe every surface to strip polishing oils. Only then coat.

That panel wipe matters more than it sounds. Skip it and the coating bonds to polishing residue instead of to paint, which is why some coatings fail within months while the same product on the next car lasts years.

The coating is the last ten percent of the work and the smallest share of the time.

The strongest coatings are not sold retail. Manufacturers release them only to installers they have trained and assessed, and the reason is practical rather than promotional.

A coating that cures to serious hardness is unforgiving. Applied unevenly, or over paint that was not properly prepared, it does not simply underperform. It locks the error in for years, and removing a failed coating is its own expensive job on top of the one you already paid for.

It also means the longest guarantees exist at all. Seven and ten year terms are only issued through authorised applicators, whoever else applies the product.

A coating behaves the same on any colour, but what you see is different. On black or dark grey the gloss and depth after correction are dramatic, and so is any swirl you leave behind, which is why dark cars need the most correction before coating.

On white and silver the coating shows itself in how the car washes rather than how it shines. Iron fallout and road film stop bonding, so the orange specks on a white bonnet stop appearing and the car stays looking clean for far longer between washes.

Either way, the coating goes on last. The colour changes how much correction sits in front of it, and that is what changes the quote.

A coating is touch dry in hours and fully cured over a week or two, and how it is treated in that window matters. Keep it dry if you can, keep it out from under trees, and do not wash it.

Water spots and bird droppings in the first days should be lifted gently with a detail spray and a soft microfibre, not rubbed. No car cover, because a cover on a curing coating can mark it.

After that the first wash is a normal two-bucket wash and the coating is simply part of the car. We will tell you when the car is handed back exactly what to avoid and for how long.

People sometimes ask for a coating to stop stone chips, and it will not. A coating is microns thick and it handles chemical attack: UV, bird droppings, fallout, water spotting. A stone hits it exactly as it would hit bare paint.

Stone chips on the front bar and bonnet edge are a job for paint protection film, a thick clear urethane, and that is a different product from a different trade. If chips are the thing keeping you awake, say so, because a coating is the wrong answer to that question.

For everything else that ages paint, the coating is the right one, and a corrected, coated car is what most people in Greenacre are actually after when they ask for protection.
