Repair cracks on the windshield So that during the work the damage does not spread further, eliminate excessive stress. To do this, from each end of the split, retreat 2-3 cm and drill small depressions from each edge (not through). On the strips of film, generously apply the composition for repair along the entire length. Using a syringe, fill the crack with polymer adhesion material from bottom to top in one direction. Under pressure, pump it into the drilled holes. Apply a film to the surface of the defective part of the glass and gently level it. Remove excess glue immediately with a clean cloth. Set the UV lamp at a distance of 10-15 cm. Leave to expose the resin for 25-35 minutes. If there is no special lamp to trigger the clutch reaction, move the car under sunlight. After the composition is fully grasped, remove the film and glue residues with a blade.
