Autumn Paint Protection: Sorting Your Ride After a Brutal Summer

Most car owners make this harder than it needs to be. Here's the straightforward approach that actually works—no fluff, no upselling.

Summer in Australia is an absolute killer for car paint, especially with the UV we get. This guide covers how to strip back the summer grime and get your protection sorted before the winter rains hit.

Autumn Paint Protection: Sorting Your Ride After a Brutal Summer

Aussie Conditions

Australian conditions are tougher than most—intense UV, red dust, coastal salt, and 40°C summers. European car care advice often doesn't cut it here.
Quick Summary

Look, we've just come off the back of another scorching summer and if your car is anything like the ones I've been seeing in the shop lately, it's copped a beating. Between the 40-degree days, the coastal salt, and those lovely bat droppings that eat through clear coat in about five minutes, your paint is probably screaming for help. This guide is for the bloke or lady who wants to fix that damage and seal the car up properly for the months ahead. It's not rocket science, but doing it right takes a bit of elbow grease.

01

Why Autumn is the Most Important Time for Your Car

Right, so summer is officially over, but the damage is already done. I reckon people underestimate just how much the Aussie sun punishes a car. I had a customer bring in a black Toyota Kluger last week that had been parked under a gum tree all February, the sap and the UV had basically baked a crust into the roof. It was a nightmare. Autumn is your window of opportunity. The weather is cool enough that your products won't dry out on the paint instantly, but it's still dry enough to get a good sealant to bond. If you leave your car with summer's leftover red dust, salt spray, and bug guts sitting on it through the wet winter, you're asking for rust and permanent etching. We're going to strip it back, clean it deep, and chuck on some serious protection. Trust me, your future self (and your resale value) will thank you.

The Gear You'll Need

What You'll Need

0/9
Two 15L Buckets — One for soapy water, one for rinsing. Don't skip the grit guards if you've got 'em.
High-quality pH Neutral Car Wash — Stick with something like Bowden's Own Nanolicious or Meguiar's Gold Class.
Clay Bar or Clay Mitt — Essential for getting that 'smooth as glass' feel after a dusty summer.
Iron Remover / Decontamination Spray — I use Gtechniq W6. It's great for getting rid of brake dust and industrial fallout.
Microfibre Wash Mitt — Don't use a sponge. Sponges are for the dishes, not your paint.
Large Microfibre Drying Towel — Something like the Big Green Sucker. Chamois are old school and usually cause scratches.
Paint Sealant or Ceramic Spray — My go-to is Griot's 3-in-1 Ceramic Wax or Autoglym UHD Wax if you like the old-school shine.
All-Purpose Cleaner (APC) — For the door jams and the greasy bits around the boot.
Wheel Brush and Tyre Shine — Because a clean car with brown tyres looks rubbish.

Getting the Foundation Right

Tap each step to mark complete
01

Find a Shady Spot

Never, ever wash your car in direct Aussie sun if you can help it. The water dries too fast and leaves spots. If the paint feels hot to the touch, let it cool down first. Grab a cold one and wait 20 minutes.

02

The Wheels First Rule

I always do the wheels first. Why? Because they're usually the filthiest part. If you wash the body first then spray wheel cleaner, all that grime and iron spray flick back onto your clean paint. Use a dedicated bucket for the wheels so you don't get brake dust in your main wash mitt.

03

The Pre-Rinse

Give the whole car a good blast with the hose or pressure washer. You want to get as much of that loose grit and red dust off as possible before you actually touch the paint with a mitt. If you've been out near the coast, pay extra attention to the wheel arches to get the salt out.

04

The Deep Clean and Protect Method

Tap each step to mark complete
01

The Two-Bucket Wash

Dunk your mitt in the soapy water, wash a panel, then rinse the mitt in the plain water bucket before going back for more soap. Start from the roof and work your way down. The bottom of the doors is always the dirtiest, so save those for last.

02

Chemical Decontamination

Once the car is washed (but still wet), spray your Iron Remover over the paint. If you see purple streaks, that's the chemical reacting with embedded metal bits from the road. Let it sit for 3-5 minutes, but don't let it dry! Rinse it off thoroughly.

03

Clay Barring

This is the secret sauce. Use a clay bar with plenty of soapy water or clay lube. Gently glide it over the paint. It'll feel 'grabby' at first, then it'll get smooth. I once did this on a mate's white Hilux that felt like sandpaper, after 20 minutes with the clay, it felt like silk. This removes the 'baked-on' summer grime that a normal wash won't touch.

04

The Final Rinse and Dry

Give it one more rinse. Then, use your big microfibre towel to dry it off. Don't rub like you're scrubbing a floor; just lay the towel flat and pat it or drag it slowly across the surface.

05

Check for Etching

Now the car is naked and clean, look for bird poo marks. If the sun has 'cooked' the mark into the paint, you might need a light polish. Most of the time, a bit of hand polish will clear up the haze.

06

Apply Paint Protection

Whether you're using a wax or a ceramic spray, do one panel at a time. If you're using a ceramic spray, usually it's 'spray on, wipe off'. Don't go overboard, more isn't better. Two thin coats are always better than one thick, smeary mess.

07

Door Jams and Seals

Open the doors and wipe down the sills. I like to put a bit of rubber protectant (like 303 Aerospace) on the door seals. Summer heat dries these out, and they'll start creaking in winter if you don't nourish them.

08

Glass Treatment

Clean the windows inside and out. If you're expecting a wet Autumn, put a rain repellent (like Rain-X or a ceramic glass coating) on the windscreen. It makes a massive difference when you're stuck in a downpour on the M1.

09

Tyre Dressing

Apply your tyre shine. Personally, I hate the 'super greasy' look. I prefer a satin finish that doesn't sling black gunk all over the guards the second you drive off.

Watch Out

Look, I've seen too many people ruin their plastic trim by getting wax or sealant on it. If you've got a modern SUV with that black plastic cladding, be bloody careful. Most waxes will turn that plastic white, and it's a right pain to get off. Either tape up the plastic before you start or use a 'trim safe' ceramic spray that won't leave white marks.

The Bat Poo Emergency

In Australia, bat droppings are basically acid. If you see one, don't wait for 'car wash day'. Carry a small bottle of quick detailer and a microfibre in the glovebox. Soak the spot, let it soften, and lift it off. Made this mistake myself on a black Commodore years ago, left a mark for three days and it ate right through the clear coat. Never again.

Watch Out

If you drop your clay bar on the ground, chuck it in the bin. Seriously. It will pick up tiny bits of gravel from your driveway, and if you keep using it, you're basically rubbing a rock against your paint. It's not worth the risk, just grab a fresh piece.

The 'Sun Check'

After you've finished applying your protection, pull the car out into the sun (or use a high-powered torch) to check for 'high spots' or smears. Some ceramic sprays can be a bit finicky and leave streaks that you won't see in the shade. It's much easier to buff them out now than it is two days later when they've fully cured.
05

Keeping the Shine Alive

Right, so you've spent the better part of your Saturday getting the car mint. To keep it that way through the rest of Autumn, you don't need to do the whole song and dance every weekend. A simple 'maintenance wash' every fortnight will do the trick. Since you've put a good base layer of protection down, the dirt won't stick nearly as much. You'll find that the red dust just hoses off. Avoid those automatic 'brush' car washes at the servo like the plague, they'll scratch your new finish in seconds. If you're short on time, use a touchless wash, but honestly, a quick 20-minute hand wash is always better. Every 3-4 months, you can 'top up' the protection with a quick spray-and-wipe sealant after your wash. Keep an eye on the water beading; when the water stops 'dancing' off the paint, you know it's time for another coat.
06

Common Questions I Get Asked

Can't I just use dish soap?
Nah, don't do that. Dish soap is designed to strip grease off pans, which means it'll strip the oils and waxes right out of your paint. It leaves the surface 'dry' and prone to UV damage. Use a proper car wash, a $20 bottle will last you a year.
How often should I clay bar?
Generally, twice a year is plenty. Over-clay barring can actually mar the paint if you're not careful. Do it once after summer and once after winter.
Is a ceramic coating worth it for a daily driver?
100%. If you're parking outside in the Aussie elements, a ceramic coating (even a DIY spray-on one) is the best defence against UV and bird crap. It makes the car much easier to clean, too.
What if I have matte paint or a wrap?
Treat it differently! Don't use waxes or polishes on matte finishes or you'll end up with shiny patches that look terrible. Use products specifically labeled for matte or satin finishes.
