If you have no experience, it is very difficult to do well. The glue hardens too quickly so I can't make a smooth surface. After treatment, it is also difficult to file, I think you should have professional tools. I have different types of sandpaper and a small rotary tool and different types of files but I still can't get the surface flat. There will also be some difference between the color and the original color. However, at this price point, a color difference is almost inevitable.
