What You'll Learn
Aussie Conditions
Look, we all know Aussie winters aren't exactly the Arctic, but they'll still do a number on your paint if you aren't careful. Between the coastal salt spray, the heavy morning dew that turns dust into mud, and the fact that our sun still burns at 20 degrees, your car needs a proper shield. This guide is for the bloke or lady who wants to spend a Saturday arvo doing it right so they don't have to worry until spring. I've been doing this for 15 years, and trust me, a bit of effort now saves a lot of grief later.
Why Winter Protection Matters Down Under
What You'll Need (The Essentials)
What You'll Need
While you're here...
The Prep Work
The Deep Clean
Give the car a massive wash. Focus on the wheel arches and the bits you usually miss, like inside the fuel door and the door jambs. Use a decent degreaser on the lower thirds of the car to get rid of any old road tar.
Iron Decontamination
Spray your fallout remover on the paint (do it in the shade!). If it turns purple, it's working. Rinse it off thoroughly. This stops those tiny metal particles from rusting under your wax during the wet months.
The Clay Bar Test
Run your hand over the paint. If it feels like sandpaper, you need to clay it. Use plenty of lube and glide the clay over the surface until it's smooth as glass. This is the difference between a 'okay' job and a pro finish.
The Main Protection Routine
Dry it properly
Use a big dedicated drying towel. Don't use an old chamois, they're rubbish and just drag dirt around. Make sure the wing mirrors and badges aren't dripping water, or they'll ruin your sealant application.
Check the surface
Take a quick look for any bird poo etching or heavy scratches. If you've got them, now is the time to hit them with a light polish. No point sealing in the damage.
Apply the Base Layer
If you're using a liquid sealant like Seal N Shine or Gyeon CanCoat, work one panel at a time. A little goes a long way. Don't go 'thick is better', it's a nightmare to buff off if you apply too much.
Buff to a Shine
Wait the recommended time (usually 1-2 minutes for modern sealants) and buff off with a fresh microfibre. Flip the towel often. If it feels 'grabby', you've waited too long.
Hit the Glass
Don't forget the windows. I always put a dedicated rain repellent (like Rain-X or better yet, a glass-specific coating) on the windscreen. In winter, having rain bead off at 80km/h is a safety thing, honestly.
Protect the Trim
Aussie sun destroys black plastic trim. Use a trim restorer that actually cures. It’ll stop the plastic from going grey and brittle after a few frosty mornings and sunny arvos.
Wheel Protection
Chuck some of that sealant on your rims too. It makes cleaning off brake dust a breeze when you're washing the car in the cold later on.
Check the Seals
Rub a bit of silicone protectant on the rubber door seals. This prevents them from sticking or cracking if you get a proper frost (looking at you, Canberra mates).
The Second Coat (Optional)
If you've got the time, wait an hour and do a second layer. It ensures you didn't miss any spots. I usually do this while having a brew in the garage.
Tyre Shine
Last step, slap on some tyre dressing. It doesn't just look good; it keeps the sidewalls from cracking in the UV.
Internal Check
Give the dash a wipe with a UV protectant. Even in winter, the Aussie sun coming through the windscreen is a killer for vinyl.
Final Walkaround
Take the car out into the sun (if it's out) and check for any high spots or streaks. Buff 'em out now before the sealant fully cures.
