Nearly every Sacramento daily driver that has not been clayed in a year needs it. You can hear it working: the surface goes from a faint grinding sound to silent as it cleans.
What claying removes
- Industrial fallout and brake dust particles embedded in the clear coat
- Tree sap residue left behind after washing, common under valley oaks and pines
- Overspray from nearby construction, painting or road work
- Hardened irrigation and sprinkler mineral deposits that a wash cannot dissolve
- Road tar film on lower panels and behind the wheels
When to clay
Do the bag test: put your hand in a thin plastic bag and glide it across freshly washed paint. If it drags or feels gritty, the car needs claying. Most vehicles parked outside in Sacramento need it once or twice a year; garaged cars, less often.
Claying is also a mandatory prep step before any sealant or ceramic coating. Protection applied over contamination fails early and traps the contamination underneath.
Claying and marring
Clay can leave very light marring on soft paint, particularly on dark colors. That is why claying is normally paired with a polish step, or done with a fine-grade medium and generous lubrication when polishing is not part of the job. We will tell you which approach makes sense for your finish.
Frequently asked questions
Is claying safe for my paint?
Yes, when done with proper lubrication and a clean medium. Dropped clay is discarded immediately — never reused.
Do I need claying before a ceramic coating?
Yes. It is a required prep step, along with chemical decontamination and usually polishing.
How long does it take?
Typically one to two hours for a standard vehicle, depending on how contaminated the paint is.
