Summer UV Damage Control: Your Post-Heatwave Checklist

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 all know the Aussie sun is bloody relentless, and by the time March rolls around, your clear coat has usually taken a fair beating. I've spent 15 years fixing 'sun-baked' paint, and honestly, most of it could've been avoided with a bit of prep. This checklist is for the blokes and ladies who want to stop their daily driver looking like an old weather-beaten ute.

01

The UV Protection Kit

What You'll Need

0/8
Quality PH-neutral car wash — Stick with Bowden's Own Nanolicious or Meguiar's Gold Class. Avoid the cheap 'wash and wax' stuff from the servo.
Synthetic Sealant or Si02 Spray — I reckon Gtechniq C2V3 is the go-to for UV. Wax melts in our 40-degree heat, don't bother with it.
Dedicated Trim Protectant — Something with a high SPF like 303 Aerospace Protectant. (Your dash will thank you).
Clay Bar or Clay Mitt — To get rid of that gritty feel from salt and red dust.
Microfiber Wash Mitt — Two of 'em. One for the top, one for the bottom grimy bits.
Large Drying Towel — Don't use an old chamois, they're rubbish and scratch the paint.
Bug & Tar Remover — Crucial if you've been driving at dusk or through the bush.
Two Buckets — One for soapy water, one for rinsing the dirt off your mitt.
02

Before You Wet The Car

What You'll Need

0/4
Check the surface temp — If the bonnet is hot enough to fry an egg, stop. Work in the shade or wait for the arvo.
Inspect for bat droppings — These are acidic and will eat through clear coat in hours. Made this mistake on a black Commodore, never again.
Check wiper blades — The heat kills the rubber. If they're crunchy, chuck 'em and get new ones.
Look for red dust in seals — If you've been out west, check the door jams and window seals before washing.

The Protection Process

Tap each step to mark complete
01

Deep Cleanse

Blast the car with water first to get the loose grit off. Use the two-bucket method to wash. Focus on the front end where the bugs bake on.

02

Decontamination

Run your hand over the paint. If it feels like sandpaper, use your clay bar with plenty of lube. This removes industrial fallout and salt spray.

03

Dry it Properly

Dry the car thoroughly. Water spots in the Aussie sun act like tiny magnifying glasses and can actually burn your paint. (Trust me on this one).

04

Apply UV Sealant

Wipe on your sealant (like C2V3 or Meguiar's Hybrid Ceramic). Do one panel at a time. This is your primary shield against those nasty UV rays.

05

Interior UV Shield

Wipe down the dash and door cards with your UV protectant. It stops the plastic from turning grey and cracking in the heat.

06

Tyre Dressing

Apply a water-based dressing to the sidewalls. It stops the rubber from 'blooming' or turning brown from sun exposure. Looks heaps better too.

04

The 'She's Right' Inspection

What You'll Need

0/3
Streak Check — Look at the paint from an angle. Any hazy spots? Buff 'em out with a fresh microfiber.
Glass Clarity — Clean the inside of the windscreen. Off-gassing from hot plastics leaves a film that's a nightmare for glare.
Trim Coverage — Make sure you didn't miss the plastic bits under the wipers, they always fade first.

A Few Truths

Look, some people swear by carnauba wax because it looks 'deep,' but in an Australian Summer, it's gone in a week. Stick to synthetics. Also, a customer once brought in a Range Rover with 'sunburn', it was just dried bore water. If you're washing with tank or bore water, dry that car fast!

Watch Out

Never apply protectants to your steering wheel, pedals, or floor mats. They'll get slippery as a greased pig and you'll end up in a ditch. Also, keep your chemicals out of the sun while you work so they don't 'go off' in the bottle.
