Assess the damage before choosing a repair
Whether a windshield can be repaired depends on the damage type, size, depth and location, the condition of the glass, and applicable repair-system and vehicle-manufacturer guidance. A trained technician can assess those factors before you choose a repair method.
Know what the repair system is designed to do
DIY kits and professional repair systems have specific application limits and procedures. Moisture, contamination, unsuitable damage and an incomplete process can affect the result.
Keep expectations realistic
Repair can improve the appearance of suitable damage and help stop it spreading, but a visible blemish may remain. Some damage requires replacement. The windshield’s contribution to crash protection varies by vehicle. Follow the applicable vehicle and repair-system guidance.
