In case of a large-shaped hole or hole, you can press the hole or hole Shape cropping.
2. Leaks and coatings are not allowed, and at the same time, it is not allowed to replace welding or glue repair with needle seams, but if the tarpaulin repaired by welding or glue repair is selected, then it is necessary to be satisfied with this Several conditions.
