Quarter Glass Replacement for Lamborghini Sian FKP 37 & Roadster (2020-2022)
Working on a Lamborghini Sian FKP 37 or its Roadster variant isn't your everyday auto glass job. With only a handful of these hybrid V12 hypercars out there, a shattered quarter glass is a massive headache. I've spent years pulling panels and laying glass, and I can tell you straight up: you don't let just anyone touch a 2020-2022 Sian. You need a technician who understands the exact tolerances of Lamborghini's carbon-fiber monocoque and respects the engineering behind the car.
Our Step-by-Step Replacement Process
Replacing the quarter glass on a Sian requires an incredibly steady hand and absolute focus. Here is exactly how we get the job done right the first time:
- Interior and Exterior Protection: First things first, we protect the car. The Sian is packed with exposed carbon fiber, bespoke leather, and Alcantara. We mask off the surrounding body panels with low-tack tape and drape the interior with heavy-duty protective covers before a single tool comes out.
- Precision Glass Removal: We never use traditional cold knives or aggressive pry tools on a vehicle like this. Instead, we run a specialized cold-wire cutting system to gently slice through the old urethane. This pulls the damaged glass out cleanly without scratching the paint or damaging the carbon weave underneath.
- Surface Cleaning and Prep: Once the broken quarter glass is out of the way, we trim the old factory adhesive down to a flat, even layer of about one to two millimeters. We vacuum out any micro-shards of glass from the crevices and clean the pinch weld thoroughly with a specialized solvent.
- Primer Application: Any exposed body material gets a fresh coat of high-grade automotive glass primer. This step guarantees the new adhesive bites hard and prevents any long-term degradation or moisture build-up.
- High-Quality Adhesive Installation: We lay down a thick, consistent V-bead of premium, fast-curing urethane. Then, we carefully set the new OEM-spec quarter glass exactly into place, pressing it in to ensure the panel gaps match the factory lines perfectly.
