Devices for covering up the effect of a pockmark in the outer layer of a safety glass windshield or the like include means for evacuating the atmosphere around the pockmark; sealing off the immediate area surrounding the pockmark; applying a highly-penetrating transparent liquid under pressure to the sealed area to force the liquid to penetrate the crevices of the fracture surrounding the pockmark. The transparent liquid fills the microscopic crevices surrounding the pockmark and then is hardened to make the pockmark permanently transparent and effectively invisible as one looks through the safety glass.
