Ceramic Coating
How We Do It

This isn't a quick spray wax. A ceramic coating is a semi-permanent layer of protection bonded directly to your clear coat — and getting it right takes prep, correction, and precision.

The 5-Stage Process

What We Actually Do

Every ceramic coating appointment follows these 5 stages, in order. The preparation work takes more time than the coating itself — and that's the point.

Stage 03

Panel Wipe

After correction, all polishing oils and residue are fully stripped from every panel using an IPA (isopropyl alcohol) wipe-down. This step is critical — any oil left on the surface will prevent the coating from bonding correctly. We work panel by panel.

This is a step many detailers rush or skip. We do not.
Stage 05

Cure & Aftercare

After application, the coating needs time to fully cross-link and cure. You'll receive aftercare instructions specific to the product applied.

  • 24 hours minimum before any water contact
  • 7 days before washing
  • 2–4 weeks to reach full hardness
  • Avoid automated car washes permanently
  • Annual or semi-annual top coat spray to maintain hydrophobics
We send written aftercare instructions with every coating appointment.
Common Questions

Ceramic Coating FAQ

It depends on the product. Gyeon Q² CanCoat EVO is rated by Gyeon at up to 12 months, Gtechniq EXO v5 at 18 to 24 months, and Gtechniq Crystal Serum Light at up to 5 years. Bay Area salt air and fog reduce all of those without proper upkeep — an annual top coat spray maintains the hydrophobics.
Correction is not required but strongly recommended. A ceramic coating is semi-permanent — it will seal whatever is underneath it. If your paint has swirl marks, light scratches, or oxidation, those defects will be locked under the coating unless removed first.
No. Automated car washes use stiff nylon brushes that scratch clear coat — coated or not. After a ceramic coating, hand washing or touchless washing only. This is non-negotiable if you want the coating to last.
A basic coating with a single-stage correction typically takes 6–8 hours. A full multi-stage correction plus coating on a larger vehicle can take 2 days. We'll give you a time estimate when we quote the job based on your vehicle's condition.
Yes — especially in SF. The combination of UV exposure, salt air from the Bay, and parking in tight spaces makes paint take a beating. A ceramic coating reduces maintenance time dramatically (rain sheeting, self-cleaning in most conditions) and preserves your car's resale value.
