Replacing the Roof Glass on a 2018-2020 McLaren Senna & Senna GTR
Working on a 2018-2020 McLaren Senna isn't your everyday auto glass job. You're dealing with a track-focused hypercar built completely around a highly sensitive carbon fiber tub. When the upper roof glass panel takes a hard rock impact out on the track or the highway, you need a technician who knows exactly how to handle exotic materials. One slip of a wire or cold knife, and you've damaged an incredibly expensive carbon roofline.
I've been swapping glass on high-end exotic cars for years. If you own a Senna in the Greater Toronto Area (GTA), you likely don't want it sitting in a dusty shop waiting area. We bring our specialized mobile service straight to your climate-controlled garage, whether you keep the car in Vaughan, Richmond Hill, or Markham.
Our Exact Replacement Process
We don't cut corners on a daily driver, and we certainly don't take risks on a Senna GTR. Here is exactly how we handle the sunroof replacement from start to finish:
- Interior Protection: Before any tools come out of the truck, we cover the Senna's Alcantara racing seats, steering wheel, and carbon fiber dash with heavy-duty protective blankets. We tape off the exterior edges to protect the clear coat.
- Precision Removal: We use an advanced fiber-line cutting system rather than traditional metal blades. This specialized string slices through the old factory urethane holding the sunroof without putting a single scratch on the surrounding carbon fiber canopy.
- Surface Cleaning: Once the broken glass is lifted out, we trim the existing urethane bead down to a flat 1-2mm base. We then clean the entire pinch weld using specialized lint-free prep wipes to remove dust, grease, and track debris.
- Primer Application: We apply a high-grade glass primer to the edge of the new OEM roof panel and touch up any bare spots on the vehicle frame. This step guarantees the new glue will actually bite and hold under extreme driving forces.
- Adhesive Installation: We run a thick, consistent V-bead of premium, fast-curing urethane adhesive. Two technicians then carefully drop the new sunroof into the exact factory position, securing it with retention tape until the glue fully cures.
