Fixing Scratches Without Ruining Your Paint (Mar 2026)

The easiest way to tell if you're stuffed is the fingernail test. Run your nail across the scratch. If your nail catches in the groove, it's likely too deep to polish out completely. I learned this the hard way on a black Commodore years ago, spent three hours buffing only to realise I was through the clear. If it catches, you're looking at touch-up paint; if it doesn't, you can probably save it with a bit of elbow grease and some compound.

If you've just come back from the outback, do not touch that scratch until the car is hospital-clean. Red dust is incredibly abrasive. I had a customer once try to 'rub out' a bird poop mark while the car was still dusty from a Nullarbor crossing. He basically sanded a hole into his bonnet. Pressure wash the area first, then use a clay bar to get the microscopic grit out of the paint before you even think about polishing.

Honestly, don't waste your money on those 'as seen on TV' scratch repair pens you see at the servo. They're basically just a bit of clear resin that washes off after two goes through the local wash. If you want a real result, stick to a decent DA (Dual Action) polisher or some high-quality hand compound like Meguiar's Ultimate Compound or Bowden's Own Naked Glass if it's on a window. (Wait, don't use the glass stuff on paint, you know what I mean).

Never, ever try to buff a car in the sun, especially in a 40-degree Aussie March arvo. The panels get so hot they'll flash the product off instantly and you'll end up with a sticky mess or, worse, you'll burn right through the paint. I always tell mates to wait until the evening or do it in the garage. If the metal feels hot to the touch, she's not right for polishing.
