How to repair the sunroof of an Audi A3 8V

Let's see how to repair the sunroof of an Audi A3 8V: this roof is prone to cracks and fractures in the plastic frame, which causes water leaks into the cabin. Replacing the frame can cost up to 3,000 euros, so the video offers a solution to seal the cracks and prevent leaks. We identify the visible cracks on the surface, remove any previous repair attempts, and use a Dremel (a versatile tool that can be useful in many situations, which we can find on AliExpress with the code 1005005964661547 for the price of 20.97 euros with free delivery in 7 days) to slightly widen the gaps, creating a "V" groove to allow the filler material to penetrate and adhere better. For larger cracks, weld with metal staples across the fracture; this creates internal reinforcement. Now, let's mix the two-component epoxy resin (which we can also find on AliExpress with the code 1005008791008578 for the price of 11.85 euros with free delivery in 7 days). Apply it generously to all the cracks, ensuring it penetrates deeply and completely covers the gap and reinforcements. Apply fiberglass reinforcements soaked in resin to the repaired areas, especially at the most critical points. When the resin is dry, apply a black sealant for better aesthetic sealing. The YouTuber repeatedly states that this is a "desperate" solution, which is not definitive, but it can avoid the very costly intervention of the official workshop.
