Clean the dirt on the glass surface and dry the surface. Put on disposable gloves, find the broken part of the glass surface, and pour glass repair liquid. Take out the film and lay it flat on the cracked place, lay it flat, and move it back and forth to keep the glue smooth at the cracked place. Use ultraviolet light or the sun to heat for 2-3 hours to dry and condense the repair liquid. Remove the film and use the blade to scrape off the excess glue around it. After finishing the repair work, try to keep the glass away from water within 2 days.
