How to Machine Polish Your Car Like a Pro

Aussie Conditions

Aussie red dust is iron-rich and bonds to paint. A regular rinse won't cut it—you need proper pre-wash and pH-neutral soap to avoid scratching.
Quick Summary

Look, if you've been doing the hard yards out in the red dirt or just daily driving through the Aussie summer, your paint is probably looking a bit sad. This guide is all about taking things to the next level with a machine polisher. I'm going to walk you through the gear you actually need and the techniques I've used for over 15 years to fix everything from swirl marks to those nasty bat dropping stains. It's not as scary as it looks, trust me.

01

Let's Get Your Paint Right

Right, so you've noticed those spider-web looking scratches when the sun hits your bonnet at the servo. Or maybe the red dust from your last trip to the Prom has literally baked into the finish. Australia is absolutely brutal on car paint. Between the 40 degree days and the salt air if you live near the coast, our clear coats take a massive beating. To be honest, most people are terrified of machine polishers because they think they'll burn through the paint. I made this mistake myself on a black Commodore years ago, used a rotary polisher I didn't know how to handle and puffed! Straight through to the primer. Never again. But with a modern Dual Action (DA) polisher, it's actually pretty hard to mess it up if you follow some basic rules. We're going to get that gloss back so you can actually be proud of the rig again.

The Gear You'll Actually Need

What You'll Need

0/9
Dual Action (DA) Polisher — Don't bother with those cheap $50 ones from the big box stores; they don't have the torque. Get a decent 15mm throw DA like a Shinemate or a Rupes if you're feeling flush.
Assorted Foam Pads — You'll want at least 3 cutting pads (orange/yellow) and 3 finishing pads (black/white). I reckon the Lake Country HDO pads are the best for our heat.
A Quality One-Step Polish — For most Aussie cars, something like Scholl S20 Black or Koch Chemie P6.01 works wonders. It cuts and finishes in one go.
Clay Bar or Clay Mitt — You can't polish dirt. Use a clay mitt to get the grit off first.
High-Quality Microfibre Towels — Get at least 10. You need clean ones for every panel. The Rag Company makes some crackers.
Panel Wipe or Isopropyl Alcohol (IPA) — This removes the polishing oils so you can see if you actually fixed the scratches or just filled them.
Masking Tape — Cheap green painters tape from Bunnings is fine. Protect your plastics!
Good Lighting — A Scangrip is great, but honestly, a decent LED headlamp works if you're working in the garage.
Pad Cleaning Brush — A stiff nylon brush to flick out the dried polish every few passes.

Prep is Everything (Don't Skip This)

01

The Decontamination Wash

Give the car a proper wash using the two-bucket method. Use a strip wash soap or chuck a bit of APC (All Purpose Cleaner) in the bucket to get rid of old waxes. If you've been near the coast or outback, make sure you've blasted every bit of salt and red dust out of the cracks.

02

Clay Bar the Surface

Run your hand over the paint. If it feels like sandpaper, it's got contaminants. Use plenty of lube and a clay mitt. If you skip this, the polisher will just pick up that grit and grind it into your paint. I once saw a mate try to polish a dusty ute without claying, it looked like he'd used a scouring pad by the time he was done.

03

Tape Off the Trim

Tape up any black plastic trim, rubber seals, and badges. Polishing pads will turn black plastic white, and it's a massive pain to get off later. (The missus won't be happy if you ruin the trim on her SUV, trust me).

04

The Polishing Process

Tap each step to mark complete
01

Prime the Pad

Put 4 or 5 pea-sized drops of polish onto your foam pad. Don't go overboard; more polish doesn't mean more shine, it just makes a mess.

02

Dab and Spread

With the machine OFF, dab the pad around a small 50cm x 50cm area. This stops the polish from flinging everywhere (we call that 'sling') when you pull the trigger.

03

The First Pass

Turn the machine on at a low speed (Setting 1 or 2) and spread the polish evenly across your work area. No pressure needed, just let the machine sit there.

04

Crank It Up

Turn the speed up to 4 or 5. This is where the magic happens. You want to move the machine slowly, about 2-3 centimetres per second. If you move too fast, you won't remove the defects.

05

The Cross-Hatch Pattern

Move the machine in overlapping horizontal lines, then switch to vertical lines. This ensures you've hit every square millimetre of the section.

06

Watch the Polish Work

You'll see the polish go from creamy to a clear film. Usually, 4-5 passes is enough. If it starts getting dusty, stop, you're working it too long.

07

Wipe and Inspect

Use a clean microfibre to buff off the residue. Now, spray some IPA or panel wipe on the area and wipe again. This is the moment of truth. Check it with your light. Still see scratches? Do another set of passes.

08

Clean Your Pad

After every single section, use your brush to flick the dried polish out of the pad. If the pad gets 'caked', it won't cut, and it'll get too hot. Heat is the enemy of Aussie clear coats.

09

Switch Pads Often

Don't try to do the whole car with one pad. After 2 or 3 panels, the foam will be soft and saturated. Chuck it in a bucket of water and grab a fresh, dry one.

Watch Out

Never polish in direct Aussie sunlight. The metal gets so hot it'll bake the polish onto the paint instantly, and you'll be scrubbing for hours to get it off. Work in a garage or under a decent carport. If the panel is too hot to touch comfortably with the back of your hand, it's too hot to polish.

Dealing with Bat and Bird Bombs

If you've got those nasty etched marks from bat droppings (bloody nightmare, aren't they?), don't just keep polishing the same spot for 10 minutes. You'll burn the paint. If it doesn't come out after two goes, it might be through the clear coat. Know when to walk away.

Watch Out

Paint is always thinnest on the edges of panels and along body lines. I've seen plenty of blokes burn through the paint on a wheel arch because they got a bit cocky. Keep the pad flat and try to stay about a centimetre away from sharp edges if you're a beginner.
05

Keep it Looking Mint

Once you've finished the whole car, she'll be looking like a mirror. But you're not done yet. Polished paint is 'naked', it has zero protection against the UV rays we get here. You need to seal it immediately. I'm a big fan of ceramic sealants these days. Something like Gtechniq C2V3 or Bowden’s Own Bead Machine is dead easy to apply and will last months. If you’ve gone to all this effort, don't go through a cheap brush wash at the servo next week! That'll just ruin your hard work in thirty seconds. Stick to hand washing with a decent microfibre mitt and you'll be right for a long time.

Your Questions Answered

Can I polish a ceramic coated car?
Technically yes, but polishing will remove the coating. If your coated car has scratches, you'll have to polish them out and then re-apply the coating to that section.
How often should I polish my car?
Honestly, I wouldn't do a full machine polish more than once a year. Every time you polish, you're removing a tiny layer of clear coat. In our harsh sun, you want to keep as much clear coat as possible.
What if my pad keeps flying off?
You've probably got too much polish on it or the velcro is wet. Make sure the pad is centred perfectly on the backing plate and keep it clean.
Is a rotary or DA better for beginners?
DA (Dual Action) every day of the week. Rotaries are for guys who've been doing this for years and need to move fast. A DA is much safer and gives a better finish for most people.
Do I need to polish a brand new car?
Surprisingly, yes. Most cars come from the dealership with 'dealer installed swirl marks' from their rushed wash bays. A light finishing polish will make a new car look better than the day you picked it up.
