Hello everyone im new to this and already have a question does anyone know where to get rear window seals the one that runs along the bottom of the window? For a octavia mk3 saloon And are they easy to replace?

Since it's not a typical wear/spare/aftermarket part I would assume Skoda dealers are the only source. What happened?

Thats what i fear ill ask them when it goes in for a new badge under warranty next week, i caught it with my nail i think when i was cleaning it and gouged it like 1cm by 1mm but car is only 2 month old so feel like i need to repair it.
