Sorting Out Scratches: A Pro's Guide to Restoring Your Paint (Mar 2026)

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 all been there, you come back to the car park and find a mystery mark, or you've pushed a bit too hard through some lantana on a weekend trip. This guide is a deep dive into everything I've learned over 15 years about removing scratches in the harsh Aussie sun. We're going to cover everything from the basic 'fingernail test' to using a dual-action polisher like a pro.

01

The Reality of Aussie Paintwork

Right, let's get stuck into it. If you live in Oz, your car's paint is basically in a constant war zone. Between the 40-degree summer days that bake bird droppings into your clear coat in minutes, and that fine red outback dust that acts like sandpaper the moment you touch it, it's a miracle our cars have any shine left at all. I remember back when I started, I had a customer bring in a black VE Commodore, gorgeous car, but he’d tried to 'fix' a scratch with a kitchen scourer. Made my heart sink, honestly. He’d turned a tiny scuff into a massive patch of hazy, ruined paint. I spent six hours bringing that panel back to life. That's the biggest thing I want to drum into you today: patience is your best mate. If you rush, you'll end up at a spray shop shelling out a grand for a respray. After 15 years doing this, I've seen it all. I've seen 'magic' pens sold at servos that are nothing more than glorified clear nail polish, and I've seen guys burn straight through their paint because they thought they could use a rotary polisher after watching one YouTube video. My goal here is to give you the actual trade secrets. We aren't just talking about hiding scratches with fillers that'll wash off the next time it rains. We're talking about proper leveling of the clear coat to get that finish back to a mirror shine. Before we even pick up a cloth, you need to understand what you're looking at. Most modern cars have a 'base coat' (the colour) and a 'clear coat' (the protection). Most scratches we deal with are just in that top clear layer. If you can see metal or grey primer, give it a rest, you aren't polishing that out, you'll need a touch-up pen or a pro. But for everything else? Stick with me and we'll get it sorted.

The Gear You Actually Need

What You'll Need

0/12
Dual Action (DA) Polisher — Don't buy a cheap $40 vibrating 'buffer' from the hardware store. Get a proper DA like a Shinemate or a Rupes if you're feeling flush. It's much safer for beginners.
A high-quality Clay Bar or Clay Mitt — I reckon the Bowden's Own Fine Clay Bar is a cracker for Aussie conditions. Essential for getting the grit out before you polish.
Cutting Compound — Something like Koch Chemie H9 or Meguiar's M105. This is the 'heavy lifter' for deeper scratches.
Finishing Polish — Sonax Perfect Finish is my go-to. It cleans up the haze left by the compound and brings the gloss.
Assorted Foam Pads — You'll want at least two 'cutting' pads (usually green or orange) and two 'finishing' pads (usually black or white).
Microfibre Towels (at least 10) — And I mean clean ones! If you drop one on the ground, it's dead to you until it's been through the wash.
Isopropyl Alcohol (IPA) Wipe — Mix 15% IPA with water in a spray bottle. This strips away polish oils so you can see if the scratch is actually gone.
Clay Lubricant — Don't just use water. A proper lube stops the clay from marring the paint. Soapy water is okay in a pinch, but a dedicated lube is better.
LED Inspection Light — Even a high-powered torch will do. You can't fix what you can't see, and garage lights always lie to you.
Masking Tape (Automotive Grade) — The blue or green stuff. Use it to cover plastic trims so you don't turn them white with polish.
Panel Prep Spray — Basically a fancier version of the IPA wipe. Gtechniq Panel Wipe is brilliant.
A rolling stool — Your back will thank me later. Seriously.

Prep Work: Don't Skip This

Tap each step to mark complete
01

The Deep Clean

Give the car a thorough wash using the two-bucket method. You want every bit of dirt, salt, and grime gone. If you've been near the coast or out in the dust, pay extra attention to the gaps.

02

Decontamination

Use an Iron Remover spray (like Bowden's Wheely Clean, yeah, it works on paint too) to get rid of metallic fallout. Rinse it off well.

03

Clay Bar the Area

Rub the clay bar over the scratched panel using plenty of lube. When the paint feels as smooth as glass, you're ready. If it feels gritty, keep going.

04

Dry and Inspect

Dry the panel perfectly. Use your LED light to look at the scratch from different angles. Use the 'fingernail test', if your nail catches in the groove, it's deep. If it doesn't, it's a 'swirl' or light scratch.

05

Masking Off

Tape off any rubber seals, unpainted plastic trim, or badges near the work area. Polishing pads will chew through plastic or stain it in seconds.

The Correction Process: Step-by-Step

Tap each step to mark complete
01

Prime the Pad

Apply 4-5 pea-sized drops of cutting compound to your foam cutting pad. Spread it around with your finger to ensure the face of the pad is lightly covered.

02

Dab the Work Area

Work in a small area, no bigger than 50cm x 50cm. Dab the polisher (while off) around the area to spread the product.

03

Spread at Low Speed

Set your DA polisher to speed 1 or 2. Spread the compound evenly over your marked-out square.

04

The Working Passes

Turn the speed up to 4 or 5. Move the polisher in a slow, overlapping cross-hatch pattern (left-to-right, then up-and-down). Use moderate pressure, enough to slow the pad slightly, but not stop it spinning.

05

Watch the Flash

Keep going for about 2-4 minutes until the compound turns translucent (this is called 'flashing').

06

Wipe and Inspect

Use a clean microfibre to wipe away the residue. Don't scrub hard; let the towel do the work.

07

The IPA Reveal

Spray your IPA mix on the area and wipe. This removes the oils. If the scratch is still there, you might need a second pass with the compound.

08

Switch to Finishing

Once the scratch is gone (or as good as it'll get), switch to your soft finishing pad and polishing liquid.

09

Refine the Finish

Repeat the process but with less pressure and at a slightly lower speed (speed 3-4). This removes any 'haze' or 'tick marks' left by the heavy compound.

10

Final Wipe Down

Wipe clean with a fresh microfibre. The paint should now look incredibly deep and glossy.

11

Check with the Light

Use your LED light again. Look for any remaining 'pigtails' or shadows. If it's clear, you're golden.

12

Seal the Deal

Your paint is now 'naked'. You must apply a wax, sealant, or ceramic coating immediately to protect that fresh surface from UV.

Watch Out

Never polish in direct sunlight or on a hot panel. If the metal is hot enough to fry an egg, you'll bake the polish into the paint and it'll be a nightmare to get off. Always work in the shade or in a garage. Also, avoid 'circular' hand motions if you're doing this by hand, you'll just create new swirls. Use straight lines.

The 'Less is More' Rule

Start with the least aggressive method possible. If a fine polish gets the scratch out, don't use a heavy compound. You only have a certain amount of clear coat on your car; once it's gone, it's gone forever.
05

Advanced Trick: Wet Sanding

Look, I'm only mentioning this so you know it exists, but be bloody careful. If you have a scratch that's deep but hasn't hit the primer, you can use 2000 or 3000 grit wet-and-dry sandpaper. You soak the paper for 15 minutes, use heaps of water, and very lightly sand the scratch. It'll turn the paint completely matte/white. You then have to use a DA polisher to 'bring back' the shine. I've done this on many high-end cars, but the first time I tried it on my old ute, I went right through to the metal because I was being a cowboy. Only attempt this if you're prepared to pay for a respray if it goes wrong.
06

My Favourite Gear for 2026

I've used everything. Honestly, for the enthusiast, you can't go past the Meguiar's Ultimate Compound. It's 'diminishing abrasive' technology, which means it breaks down as you use it, making it very hard to mess up. For the pads, I reckon Lake Country CCS pads are the best in the business, they don't get too hot, which is vital in our climate. If you want a 'one-step' solution (where you don't need to do two stages), 3D One is a brilliant product that manages to cut and finish pretty well on most Aussie paints like Ford and Holden.
07

Keeping it Mint: Aftercare

Once you've spent the afternoon sweating over your paint, don't let it go to waste. In Australia, the UV is your biggest enemy. If you leave your car unprotected, that fresh clear coat will start to oxidise faster than you'd think. I always tell my customers: get a decent ceramic sealant on there at the very least. Something like Gyeon CanCoat is easy enough for a DIYer. Also, change your wash habits. Stop using the brush at the self-serve car wash! That brush has been used to scrub the mud off a 4WD's wheel arches two minutes before you touched it. It's basically a stick covered in rocks. Use a high-quality microfibre wash mitt and the two-bucket method. If you get bird droppings or bat muck on the car (which is acidic as hell), get it off immediately with some quick detailer spray and a soft cloth. Don't wait until the weekend.

Frequently Asked Questions

Can I remove a scratch I can feel with my nail?
Usually, no. If your nail 'clicks' into it, it's too deep to polish out safely. You can make it look 50-80% better by rounding off the edges of the scratch, but it won't be 'gone'.
Is it safe to use a rotary polisher?
For a pro? Yes. For a beginner? No way. Rotaries generate heat incredibly fast. On a plastic bumper, you can melt the paint in about 3 seconds if you aren't moving. Stick to a Dual Action polisher.
How often can I polish my car?
If you're doing a heavy 'cut', I wouldn't do it more than once or twice in the car's lifetime. For a light finish/polish, maybe once a year is fine. Every time you polish, you're removing clear coat.
What about those 'scratch repair' pens from the servo?
Waste of money. They're just a temporary fill of clear resin. They look okay for a week then yellow or wash off. Do it properly with a machine or don't bother.
Does toothpaste actually work on scratches?
It's a mild abrasive, so it can work on very light scuffs, but it's messy and nowhere near as effective as a $15 bottle of proper polish. Plus, it's a pain to clean out of the gaps.
