What is paint correction, and do you need it?

Paint correction is machine polishing that removes a thin, controlled layer of clear coat to level out swirls and haze. It is the difference between a car that is clean and a car that looks new under the sun.

Where swirl marks come from

Brush car washes, dirty sponges, drying with a bath towel, wiping snow off with a sleeve. Each leaves microscopic scratches. In direct sun they line up into circles around the light: swirls.

One-step polish vs multi-stage correction

How much clear coat does it remove?

Very little, but clear coat does not grow back. That is why correction is done with judgment: remove what is needed to make the defect disappear or fade, and stop. Aggressive shops can make a car look great once and leave nothing for next time.

What it cannot fix

A scratch that catches your fingernail has usually gone through the clear coat. Polishing can soften how it looks; only paint can truly fix it. Rock chips also need touch-up, not polish.

How to tell if your car needs it

Park in direct sun and look at a dark panel at an angle. If you see a web of fine circles around the sun’s reflection, you have swirls. If you are not sure, book our free 30-minute consultation and we will look at it with you.

Questions

How long does paint correction last?

The correction itself is permanent; the defects are removed. New swirls come from how the car is washed afterwards, which is why most people protect it with a coating.

Is paint correction safe for my paint?

Done with judgment, yes. We measure what is needed and do not cut more than the defect requires.
