Swirl Marks, Holograms, and Etching: What's Actually Wrong With Your Paint

Not every dull or marked-up paint job needs the same fix. Swirl marks, holograms, water etching, and scratches all show up as 'my paint doesn't look right' at a glance, but they come from different causes and need different levels of correction, and telling them apart takes about five minutes with a flashlight.

Swirl marks: the most common one

Fine circular scratches caused by improper washing or drying, visible as a spiderweb pattern under direct light, especially on darker colours. These are removed with correction-level machine polishing.

Holograms: the mark polishing itself can leave behind

Fine, grid-like lines left by a rotary polisher used incorrectly, too fast or with the wrong pad. Visible under bright light as a crosshatch pattern distinct from swirls, ironically caused by a poor prior polishing job. These are removed with a proper finishing polish.

Water spot etching: when it's not a scratch at all

Mineral deposits from water drying on the paint under sun bake into the clear coat, leaving ring-shaped marks rather than lines. Light etching can usually be polished out; deep etching sits below what safe correction can remove.

How to check your own paint before booking

Wash and dry the car, check it under direct light (a flashlight at a low angle works well) in a dim area, and look at a few panels, the bonnet, doors, and boot. Take photos in direct sunlight and send them to us, we can usually give a preliminary read on which category applies.

Frequently Asked Questions

Can I tell these apart myself without professional equipment?

Mostly, yes, a flashlight test at a low angle reliably distinguishes swirl marks from deep etching. Holograms are harder to identify on your own, but are usually explained by 'recently polished elsewhere and now looks worse.'

Are holograms permanent?

Not if caught early. They're corrected with a proper finishing polish, and ironically often show up right after a rushed, cheap 'polish' job somewhere else.

Does water etching always need paint correction?

Light surface etching often polishes out. If it's gone deep enough that safe correction can't remove it without excessive clear coat removal, the honest answer is living with faint marks or being more careful about future water spots, rather than over-correcting.
