Misconceptions
Car polishing is a trade wrapped in more half-truths than almost any other corner of the car-care world. This section takes the most common misconceptions - miracle scratch removers, peanut-butter hacks, "mirror" promises, drive-through "polishes," and the idea that modern paint never needs polishing - and says honestly what's true, what's marketing, and what will actually cost you paint.
Why car polishing attracts so much nonsense
The job is invisible when it's done well. A properly polished panel just looks "right" - deep, even, without swirl marks dancing under the sun. Because you can't see the micron or two of clear coat that was levelled off to get there, it's wide open to anyone who wants to sell a shortcut. A bottle of cream, a YouTube trick, a household food item - there's always someone claiming their version does what proper machine polishing does, in five minutes, for a fiver.
Most of these claims fall apart the moment you understand what a scratch actually is. If it's caught the clear coat, the only way to remove it is to take clear coat away around it until the surface is level again. No polish, no wax, no peanut butter can put clear coat back. They can only disguise it for a day or two - or, worse, add fresh micro-marring while they're at it.
What the myths cost you
Believing the hype isn't free. People rub at their bonnets with toothpaste, polishing compound, and kitchen sponges on the promise of a scratch fix, and then wonder why the panel looks hazy under sunlight. Others skip polishing altogether because they've been told modern cars "don't need it," and by the time the oxidation has bitten in, the only option left is paintwork correction at the deep end. And somewhere in the middle sits the customer who paid for "a polish" at a valet or a drive-through and got a coat of filler-heavy wash-and-wax that washed off three weeks later.
The misconceptions in this section are the ones we see causing the most damage, week in, week out, in the workshop. Each article tackles one head-on.
