Jnz Detailing is a mobile car detailer, based on Boon Tiong Road in Tiong Bahru, that comes to wherever your car is parked. There is no drop-off and no waiting room. Its work covers ceramic coating, paint correction for swirl marks and scratches, polish and wax, and glass work, including windscreen scratch and stain removal and wiper mark removal. For hard water spots and fallout, it offers a separate treatment. The service runs islandwide, seven days a week, from 8am to midnight, and to 1am on Saturdays. Bookings start on WhatsApp, where the detailer quotes once he knows the car and the paint condition. Customers say replies are prompt and that a next-day slot was confirmed quickly. One full ceramic coating was finished at a home in about three hours. A windscreen treatment left one driver seeing much better under street lights at night. The detailer tells customers in advance what the paint can achieve. One customer was told the result would be about 80% of like-new, and was happy with it. Paint correction comes first, so the coating sits on corrected paint. Of the two mechanics nearby with ten or more reviews, neither rates higher. Motoserv on Havelock Road, 0.7 km away, is rated the same. The base address is 8C Boon Tiong Road, Singapore 166008.
