Wax vs Sealant: Protecting Your Paint in the Aussie Summer (Feb 2026)

Give the car a proper wash using the two-bucket method. You want to get every bit of road grime and salt off. If you've been near the beach, pay extra attention to the wheel arches and sills.

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 makes the sealant bond way better.

Give the car a quick wipe with your IPA mix. This removes any leftover soaps or old wax. It’s a step most people skip, but it’s the secret to making a sealant last 6 months instead of 6 weeks.

I cannot stress this enough. Do not apply wax or sealant in direct Aussie sun. The product will flash (dry) instantly and you'll be scrubbing for hours to get the streaks out. Wait for the arvo or do it in the garage.

Put a few small drops of product on your foam applicator. You don't need much. If you're using a paste wax, just a light swipe in the tub is plenty.

Start with the roof or bonnet. Work in small sections, roughly 50cm by 50cm. Don't try to do the whole car at once or the first bit will be a rock by the time you get back to it.

For sealants, I like straight lines (up and down, then side to side). For waxes, old-school circular motions are fine. The goal is thin, even coverage. If you can see thick white globs, you've used too much.

Most products need 5-10 minutes to 'cure' or haze over. It'll look a bit cloudy when it's ready. In our humidity, this might happen faster than the bottle says.

Run a clean finger through the haze. If it smears, it’s not ready. If it wipes away clean to reveal shiny paint, it’s time to buff.

Use a clean, plush microfibre towel. Light pressure is all you need. Flip the towel often to a clean side so you aren't just pushing old product around.

Grab a torch or use the sun (once you've finished) to check for 'high spots' or oily patches. Give them a quick buff with a fresh towel.
