What ceramic coating actually is
A ceramic coating is a liquid polymer that bonds to the clear coat and cures into a hard, slick layer. It is not a wax and it is not a sealant — it lasts years rather than weeks, sheds water rather than beading briefly, and makes the paint far easier to keep clean. It goes on last, over paint that has already been corrected, because a coating locks in whatever is underneath it.
What it will not do
A coating does not fill scratches, remove swirls or hide etching — it seals the surface as it finds it. That is why correction comes first, and why we assess before quoting rather than selling a coating to paint that is not ready for one.
Why it matters in San Francisco, CA
San Francisco does not rust cars the way a salt-belt city does — it corrodes them slowly and quietly. On the west side, from the Outer Sunset and the Richmond out to Sea Cliff and Lands End, fog carries salt off the Pacific and does not burn off, so a car parked outdoors stays damp most of the day for most of the year. Brake rotors on a car that has sat for a week come up orange. Chrome and polished trim pit. Window seals and roof-rack rubber grow a green algal film that is biological, not dirt. Nothing dries: an interior that got wet in November is still faintly musty in January, and the smell lives in the carpet backing and seat foam rather than the air. On the east side the problem inverts — Bernal, the Mission and Potrero get real sun, and the long dry stretch from May to October lets fine grit build on the paint that turns to slurry in the first serious rain. Sand blows inland off Ocean Beach. Eucalyptus and ficus drop sap and staining debris. And every hill in the city is a brake-dust generator, which is why wheels here load up on cars that barely leave the neighbourhood.
Where the work happens
The operational reality of San Francisco is that most cars have nowhere to be worked on. Garages are the exception. Victorians and Edwardians in Noe Valley, the Castro and the Richmond typically have a single tandem garage behind a low door that a service van cannot enter, and often cannot park in front of without blocking the curb cut. Towers in SoMa, Mission Bay and Rincon Hill have structured parking with a clearance bar well under seven feet. That leaves the street, and the street here is governed by three things at once: the posted street-cleaning window, which on many blocks comes twice weekly and which SFMTA enforces without much sentiment; the residential parking permit zone; and the grade, because a car on a Russian Hill or Corona Heights block has to be curbed and a work area has to be level enough to be safe. In practice the booking is matched to a legal, level spot near the car, and the sweeping schedule for that exact block is the first thing to check.
Premium paint work needs more time and better light than a standard detail, so where the vehicle sits matters more than usual. A garage or covered bay is ideal; we will tell you at the assessment if your spot will not do the paint justice, rather than working around it and charging you for the result.

Local rules we work to
San Francisco is unusual and the difference matters. The SFPUC describes San Francisco as the only coastal city in California with a combined sewer system, meaning that on most blocks the catch basin at the corner carries rain to the same treatment plants that handle household wastewater. But it is not uniform: the SFPUC identifies newer separate MS4 storm drain areas — Aquatic Park, Candlestick Point, the Embarcadero, India Basin, Mission Bay, Lake Merced, Ocean Beach, Sea Cliff and Treasure Island — where stormwater flows directly to the bay or ocean without treatment. San Francisco's sewer requirements prohibit discharging water containing pollutants, or water from sources other than rain, into storm drains and catch basins. Bay Area guidance for mobile cleaning businesses is consistent across the region: contain and divert wash water so it does not run into gutters or storm drains, and discharge it into a cleanout, sink or other drain connected to the sanitary sewer — never a storm drain. There is also a free Bay Area Municipal Stormwater Collective training and certification for mobile cleaners. The specific Public Works Code section is deliberately not quoted here. What we can state plainly: the van reclaims all of its wash water on board and disposes of it to sanitary sewer, so it does not depend on which drainage zone your block sits in.
How a job runs
- Assessment first. We look at the paint — depth readings, what the defects actually are, whether the clear coat can take correction at all.
- A quote against what we found, not a package price. Correction and coating are quoted together, because doing one without the other rarely makes sense.
- Staged work. Cut only as far as the defect needs, then refine.
- Protection last, over paint that is ready for it.
