A windshield repair device for repairing imperfections, in the form of bull's eyes, chips or cracks, induced by road hazards. The device comprises a first vacuum device for repairing relatively large imperfections, a second vacuum device for repairing relatively small imperfections adjacent the windshield periphery, and a platen to secure the second vacuum device to the windshield. The first vacuum device evacuates a relatively large area over a chip or crack and injects ultra-violet light-settable polymer resins into the evacuated imperfection. The second vacuum device is essentially the inner portion of the first vacuum device and is capable of evacuating a much smaller area. The second vacuum device is primarily useful either at the periphery of the windshield, or on areas of windshields having a high degree of curvature. The platen assists in holding the second vacuum device to the windshield.
