Trick with Eva rubber or foam rubber : This trick is useful when the bag has a hole, a point where the leather has emptied. Apply a little glue to the area to be treated and fill with EVA rubber or foam rubber. Let it dry and apply fabric paint over it . After 2 hours, spread a layer of white Resistol or transparent nail polish on the surface.

If when it has dried you notice that the repaired part is a little shinier than the rest, you can apply a little talcum powder and remove the excess with a brush.
