JnJ Detailing
Halesowen — 5(205)
XPEL certified
British ceramic coating brand and the most visible name in the UK detail scene. Crystal Serum Ultra is hand-applied only by Gtechniq Accredited Detailers — a deliberately small, vetted network. The accreditation matters more here than for any film brand.
Two-layer ceramic system, 9-year warranty, accredited-only application.
C2v3 · EXOv5
9-year warranty on Crystal Serum Ultra when applied by an accredited detailer. Self-applied versions exist (CSL, EXOv5) but the warranty drops accordingly.
Gtechniq publishes its Accredited Detailer list on gtechniq.com — if the installer isn't on it, they cannot apply Crystal Serum Ultra. Other Gtechniq products can be applied by anyone.
Cross-checked against the official Gtechniq locator where one exists, plus website badges and Google Maps signals. Verified marks (✓) on installer cards mean we found the listing on the brand's own site, not just a self-claim.
