Review on 4-Piece Universal Carbon Fiber Car Door Bowl Stickers | Protective Films 🚗 for Scratches | Car SUV Paint Protection with Door Bowl Guard Film (Silver) by Adrian Hayes

2015 Nissan Altima. Whatever material they are made of, it is very difficult to fit them without leaving creases and air bubbles in the material if you have a lot of concave surfaces under the doorknobs. It doesn't want to take the form of a door. I spent 45 minutes on Set 4 and the material was still wrinkled. I could only try to have as few wrinkles as possible. They will likely work well if you have a flat surface under the doorknobs rather than a concave one. I'll leave them until I find another set that works better for the concave shape.
