Summer UV & Salt Protection Checklist (Mar 2026)

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

Our Aussie summer is brutal on paint, from 40-degree heat to salty coastal air. This checklist covers the gear and steps needed to shield your pride and joy from UV damage and those nasty bat droppings.

Summer UV & Salt Protection Checklist (Mar 2026)

Aussie Conditions

Living near the coast? Salt air corrodes metal and degrades rubber seals. A fortnightly wash underneath is essential, not optional.
Quick Summary

Look, if you've ever seen a red Commodore with the clear coat peeling like a bad sunburn, you know why this matters. Between the intense UV and the salty breeze if you're near the coast, your paint is fighting a losing battle without protection. I've put this together so you can get in the garage, get the job done, and know your car is sorted for the rest of the hot months. It's all about creating a sacrificial layer so the sun eats that instead of your factory finish.

01

The Gear You'll Need

What You'll Need

0/8
Quality Strip Wash or APC — To kill off any old waxes. I reckon Bowden's Own Nanolicious is great for maintenance, but use a bit of 'Agent Orange' if you need to strip old junk off.
Clay Bar or Clay Mitt — Essential if you've been driving through red dust or parked under gum trees.
Iron Remover — Gets the brake dust and fallout off before you seal it in.
Synthetic Paint Sealant or Ceramic Spray — Avoid cheap 'carnuaba' waxes in 40-degree heat; they melt. Stick to something like Gtechniq C2V3 or Meguiar's Hybrid Ceramic.
UV Protectant for Trim — 303 Aerospace Protectant is the gold standard here. Don't let your plastics turn grey.
Microfibre Applicator Pads — Grab a 5-pack, you'll go through them.
At least 4 clean Microfibre Towels — High GSM (plush) for buffing off the sealant.
Window Cleaner (Tint Safe) — Because nobody likes sun-glare on a greasy windscreen.
02

Pre-Start Checklist

What You'll Need

0/4
Check the surface temp — If the bonnet burns your hand, don't start. You'll just bake the product on and have a nightmare of a time buffing it off.
Assess for Bird/Bat Droppings — If they've already etched the paint, you'll need a light polish first. I once left bat poo on my ute for two days in Brisbane heat, it ate straight to the primer.
Find some shade — Do not do this in the direct sun. Your carport or a gazebo is your best mate here.
Check the forecast — Make sure there's no rain (or dust storms) coming for at least 12 hours while the sealant cures.

The Game Plan

Tap each step to mark complete
01

The Deep Clean

Wash the car thoroughly. Use a two-bucket method to avoid swirls. If you've been out west, spend extra time flushing the red dust out of the wheel arches.

02

Decontamination

Spray iron remover on the paint. Rinse. Then use your clay bar with plenty of lube. The paint should feel smooth as glass before you move on.

03

Dry it Properly

Use a dedicated drying towel or a leaf blower. Trapped water dripping out of side mirrors will ruin your sealant bond. Believe me, it's annoying.

04

Apply UV Protection

Work in small sections (half a door at a time). Apply your sealant or ceramic spray using a microfibre applicator. A little goes a long way.

05

The Buff Off

Wait the recommended time (usually 30-60 seconds) and buff off with a clean towel. Flip the towel often to avoid clogging it with product.

06

Trim and Tyres

Apply UV protectant to all black plastics and rubber seals. This prevents that nasty cracking we get from the Aussie sun.

04

Final Inspection

What You'll Need

0/3
The 'Sunlight Test' — Pull the car out and check for high spots or 'shadowing' from the sealant. Buff them out immediately.
Wiper Blades — Give them a wipe with a damp cloth. UV kills them fast, so if they're crunchy, swap 'em now.
Interior Check — Did you remember the dash? A sunshade is good, but a wipe of 303 Protectant is better.

A Few Tips from the Trade

Honestly, don't waste your money on those '5-year' dealer coatings unless you're actually going to maintain them. I've seen 'lifetime' coatings fail in six months because the owner never washed the salt off. A good $30 bottle of spray sealant used every three months will beat a neglected $1000 coating every single time.

Watch Out

Never apply sealants or waxes to a hot surface. It'll flash instantly, leave nasty streaks, and you'll spend your whole Sunday trying to polish it off. Also, keep the chemicals off your glass unless the bottle specifically says it's okay, otherwise, your wipers will chatter like a skeleton on a tin roof.
