The Best Argument for Ceramic Coating Just Landed on My Bonnet

People ask me all the time whether ceramic coating is worth it. And I always say yes — but I’m aware that sounds exactly like what someone who sells ceramic coatings would say.

So let me tell you what happened on my own truck this week, because I think it makes the case better than any product description could.

My parking situation — and a recurring problem

I park my work truck under an overhang at our Rosedale workshop.  Sometimes it keeps the rain off, which is great. What it doesn’t keep off is the local sparrow population, which has apparently decided the overhang is prime real estate.

Bird droppings on a vehicle aren’t just unpleasant to look at. They’re genuinely damaging. The combination of uric acid and lime in bird waste is corrosive — and it gets to work on paint surfaces quickly, especially in warm weather. Leave it long enough, and you’re not looking at a mark that wipes off. You’re looking at etching that goes right into the paint surface itself, and that kind of damage is extremely difficult to address without repainting the panel.

Over the years I’ve seen this damage on a lot of customers’ cars. Certain paints seem particularly vulnerable — BMW paint and Navara paint are two I’ve noticed repeatedly. Dark colours, black especially, show the effects badly. A patch of etched paint on a black bonnet is hard to miss and even harder to fix.

• Bird droppings are one of the most underestimated causes of paint damage we see. People think it’s just cosmetic. It isn’t — left long enough, the etching goes deeper than any detail or polish can reach.

The test I didn’t really plan to run

CarPro recently updated our most entry-level ceramic coating — our most accessible and affordable protection option — and I’ve been quietly testing it on my own truck to get a feel for how it performs in real conditions before we put our name behind recommending it more widely.

Earlier this week, the sparrows obliged with a fairly generous contribution to the test. Bird droppings landed on the bonnet — a recently polished black surface — and, if I’m being honest, I left them there longer than I should have. Almost a full week, as it turned out. I wasn’t being scientific about it. I was just busy, and then a bit nervous about what I might find when I finally got around to looking.

What I found was nothing. Or rather, nothing bad.

I rinsed the bonnet with water. The droppings came straight off. No marks. No etching. No visible sign that they’d been sitting on a black painted surface for nearly a week in sunny Auckland autumn conditions. The paint underneath looked exactly as it had before.

• That result genuinely impressed me — and I’ve been in this industry long enough that it takes something real to do that. Our entry-level coating, protecting against a week of bird droppings on a black truck. Job done.

Why this matters for New Zealand drivers specifically

NZ is a green country. That’s one of the things that makes it a great place to live — the wide open spaces, the farms, the parks and reserves, the tree-lined streets, the harbors. It also means birds, everywhere, all the time.

You genuinely cannot park in most parts of Auckland without being at some risk of bird droppings landing on your vehicle. Whether it’s a weekend at the beach, a morning at the office, or an afternoon at the supermarket — if there are trees nearby, the birds are there too.

For most people, the response is to wipe it off when they notice it and hope for the best. That works, most of the time, for paint in good condition. But the risk is real, the damage accumulates, and some paint surfaces are far less forgiving than others.

A ceramic coating changes that equation. It creates a protective layer over your paint surface that resists the chemical effects of bird droppings — and a lot of other contaminants besides. The droppings still land. They just don’t get the opportunity to do their damage before you get to them.

What ceramic coating is — and what it isn’t

Ceramic coating is not a force field. It won’t prevent every form of paint damage, and it doesn’t mean you can leave bird droppings on your car indefinitely. However it does meaningfully extend the window between contamination and damage — giving you time to deal with things before they become problems.

It also makes your car considerably easier to keep clean. Ceramic-coated surfaces are hydrophobic — water beads and runs off, taking surface grime with it. Your car stays cleaner for longer between washes, and when you do wash it, the process is quicker and gentler on the paint.

For the long-term condition of your vehicle’s paint — and therefore its appearance and its value — ceramic coating is one of the most practical investments you can make. Our entry-level option makes that protection accessible at a price point that surprises most people when they hear it.

If you park under trees, near the water, or anywhere where birds frequent — this is worth a conversation. Come on in and we’ll show you what the options look like for your vehicle.
