Autumn Paint Prep: Getting Your Ride Ready for the Cooling Temps

Your paint is under constant attack: UV rays, bird droppings, tree sap, and road grime. Protection isn't optional—it's essential.

Summer's finally buggering off, but the Aussie sun is still brutal. Here is how to clean up the summer damage and get some protection on your paint before the winter rain and coastal salt kick in.

Autumn Paint Prep: Getting Your Ride Ready for the Cooling Temps

Aussie Conditions

Our intense UV breaks down waxes faster than overseas. Ceramic coatings last longer, but even they need topped up more frequently here.
Quick Summary

Look, we're heading into March and the weather is finally starting to turn, but don't let that fool you. This is actually the most important time of year to look after your paint because you've likely got three months of baked-on bugs and salt sitting there. I'm going to show you how to strip that summer filth and put down a layer of protection that'll actually last.

01

Why March is the Real Danger Zone

Right, so everyone worries about the 40 degree days in Jan, but for me, March is when the real damage shows up. You've got all that red dust from your summer road trips and bat droppings that have been slow-cooking on your bonnet for weeks. If you don't shift that stuff now, the moisture from the coming winter is going to turn those contaminants into a nasty abrasive paste. I reckon a bit of effort now saves you a massive polish job in six months.

Decontaminate or Don't Bother

I learned this the hard way when I tried to wax a black Commodore that had been parked under a gum tree all summer. The wax just smeared the sap around and looked like a dog's breakfast. Before you put any protection on, you've gotta use a clay bar or a clay mitt. If you run your hand over the paint and it feels like sandpaper, that's embedded grit. Get a clay mitt and some lube (I'm a big fan of Bowden's Own Three Way) and get it smooth as glass first.

Ditch the Old School Carnauba Wax

Honestly, I wouldn't bother with traditional waxes in the Aussie heat. They're great for show cars, but they melt off in about a week when the temp hits 35. For our conditions, you want a synthetic sealant or a ceramic spray. My go-to at the shop is Gtechniq C2, it’s dead easy to apply and shrugs off that coastal salt spray like nothing else. It’ll give you 4-6 months of legit protection while you're busy with footy season.

The 'Bat Poo' Emergency Kit

If you live near the coast or anywhere with fruit bats, you know their droppings are like battery acid. A customer once brought in a brand new Ranger with permanent etchings after just two days in the sun. Keep a bottle of quick detailer and a clean microfibre in your glovebox. If you see a hit, spray it immediately. Don't wait until the weekend or it'll eat right through your clear coat. (trust me on this one)

Don't Forget the Rubber

Most blokes forget the window seals and door rubbers. After a long, dry summer, they get brittle. Chuck some UV protectant on them, something like Aerospace 303. It stops them from cracking when the cold winter mornings start hitting. It takes two minutes and stops those annoying wind whistles on the highway.

The Autumn Protection Essentials

What You'll Need

0/4
Good quality pH neutral car wash — Avoid the cheap 'wash and wax' stuff from the servo.
Clay mitt or clay bar — Essential for removing the summer grit.
Synthetic sealant or Ceramic spray — Needs to be UV resistant for the midday sun.
Microfibre drying towel — Washing and not drying is how you get those nasty water spots.

Watch Out

Don't ever wash your car with dish soap. I see this all the time. It's designed to strip grease off pans, which means it'll strip every bit of protective oil and wax off your paint, leaving it bone dry and prone to oxidation. Also, don't wash your car in the direct 1pm sun, you'll just bake the soap onto the panels and end up with a mess that's a nightmare to fix.

Common Questions from the Shed

Is a ceramic spray as good as a proper glass coating?
Nah, not even close. A professional coating will last years, whereas a spray lasts months. But for most daily drivers, a spray is heaps better than nothing and way cheaper. It's perfect for a quick refresh between seasons.
How do I get red dust out of the crevices?
Use a soft detailing brush and some soapy water while you're washing. If you just blast it with a pressure washer, you'll often just force it deeper into the seals. Take your time around the badges and window trim.
Do I really need to polish before sealing?
Only if you want to get rid of scratches. If the paint is already in good nick but just feels rough, a clay bar and a good sealant is plenty for a winter prep. No dramas.
