To get a straight line, glue the repaired area on both sides with adhesive tape, leaving only the damaged thread itself open.
Shake the bottle before applying the polish so that no silvery residue remains on its bottom.
Apply a sufficient layer of varnish with a thin brush. In case of applying several (no more than three) layers, observe the drying time of each layer.
If a drip does form, it can be removed with a knife or razor blade after a few hours, when the product has completely hardened.

The adhesive tape used as a guide can only be removed approximately one hour after application. The tape is torn off by applying force perpendicular to the thread in the direction of the arrow (pic. 8.54). At an air temperature of 20°C, the varnish dries completely after three hours. At lower temperatures, the drying time is slightly longer.
