Car Detailing for BMW 4 Series

Detailing your BMW 4 Series

The 4 Series is the style pick in the 3 Series family, and owners tend to notice paint defects more than most. Soft clear coat plus Toronto winters means swirls and salt etching on the hood and roof, which a careful polish and a durable sealant handle well. The big grille on newer cars traps bugs and sand, and soft-top convertibles need a fabric cleaner and water repellent rather than anything we would use on paint.

What we watch for on a 4 Series

• The large vertical kidney grille on 2021 and newer cars collects bugs and road grit in dozens of slats, so we clean it with a soft detailing brush and foam rather than pressure alone
• Frameless windows leave a line of grime where the glass meets the roof seal; we clean the seal channel so the glass stops streaking after rain
• Current convertibles have a fabric roof that needs a fabric-specific cleaner and protectant, while 2014–2020 hardtop convertibles have drain channels that clog with leaves
• Low front bumper lip scuffs on underground garage ramps, so we check it for scrapes before polishing and advise on paint protection film
• Rear seats in the coupe are hard to reach, so crumbs and salt build up in the rear footwells under the front seat rails

Luxury cars: soft paint, delicate trim

Premium interiors use more leather, open-pore wood and gloss trim, and premium paint is often softer. We use gentler chemistry, soft microfibre and slower machine passes so nothing is marred.
