Our Auto Glass Nano Repair Fluid contains epoxy resins, solvents and polishes. It preserves the look and safety of the vehicle and also avoids the expense of replacing a potentially expensive full windshield in the future. Its use is simple: First clean the area around the damaged car glass, then use a blade to cut the cured film according to the broken length, and then apply the repair solution along the damaged area of the glass crack, and quickly cover with the cured film, press out the bubbles between the glass and the cured film, move the car to the direct sunlight for 10-30 minutes or use ultraviolet lamp instead of curing until curing, and then tear off the cured film. It can save the inconvenience of long maintenance or service appointments.
