Abstract
Abstract A repair method for repairing stone or gravel impact damages on windshields of multi-layer safety glass, in which the damaged place is covered with a transparent suction cup, a vacuum is produced underneath the suction cup and a liquid-clear hardening synthetic resinous material is applied onto the damaged place by means of an injection needle pierced through the suction cup. Compared to known repair methods, the method of this invention requires a lesser apparatus expenditure and can be carried out in a more simple manner.
