To scratch

A transparent body blank is put on top of the finished chassis, and the places where holes will be made by marker are marked with a marker. For drilling holes, you can use conical scanning. After the body was cut off, its edges should be polished with a small sandpaper. We take the bank (you can any, for example, from beer or cola), wrap it with an sandpaper, fix it with tape and proceed to work. The main thing is to work carefully so as not to scratch the outer layer of the protective film.
