ABSTRACT:
A device for repairing damages caused by stones on windshields comprises a syringe (10) the discharge opening (14) of which is inserted into an applicator (11) adhesively affixed to the windshield (29) by means of a sealing disk (12). The syringe (10) is pre-filled by the manufacturer with a predetermined amount of a liquid synthetic resin which is curable by light. By retracting the syringe plunger (17), a vacuum is created for removing air and moisture that may have penetrated into the damaged portion (30). In its rearmost position, the plunger (17) exposes a vent hold (23) formed in the wall of the syringe casing (13) so that the resin will then be urged into the damaged portion (30) by the ambient atmospheric pressure.
