Quick answer: Windshield repair is appropriate only after a technician confirms a repairable laminated-glass break, acceptable location and condition, removable contamination, and an approved system. ANSI/AGSC/NWRD/ROLAGS 002-2022 offers edition-specific criteria, but applicable law, vehicle and OEM technology information, technician judgment, and the exact repair-system, resin, and lamp instructions still control. Replace or refer the windshield whenever one of those checks fails.
1. Can a bullseye break be repaired?
Some bullseye breaks can be repaired, but the circular shape alone is not approval. Under ANSI/AGSC/NWRD/ROLAGS 002-2022, a diameter no larger than 1 inch (25 mm) is an edition-specific screening criterion. Do not treat that number as a universal limit; the edition's other repair limitations, applicable law, vehicle technology and OEM information, technician judgment, and the exact repair-system, resin, and curing-lamp instructions still apply. Inspect those conditions before proceeding. The full repair guide explains the complete decision path.
2. Can a star break be repaired?
A star break may be repairable when every radiating leg is visible, stable, and within the criteria being applied. The official ROLAGS damage summary gives the named edition's break-diameter criterion, but it does not override location, contamination, glass-layer, law, or vehicle-technology restrictions. Stop if a leg cannot be assessed or the system is not intended for that break. Inspect and trace all leg tips, then confirm the applicable standard and exact repair instructions.
3. Can a combination break be repaired?
A combination break can be considered only after its central body and every attached leg or crack are classified. When the pattern mixes bullseye, star, or crack features, the 002-2022 body-diameter criterion is only the first screen; three or more long cracks from one impact point is a replacement condition in that edition. Do not measure only the center. Document the full pattern, check all other limitations, and use the exact system procedure before repair.
4. Can a long windshield crack be repaired?
A long crack is not automatically repairable. The ROLAGS definitions call a crack longer than 6 inches (150 mm) long, while 002-2022 lists 14 inches (350 mm) as its edition-specific maximum crack criterion. Those values are not universal permission; the edition's other repair limitations, applicable law, vehicle technology and OEM information, technician judgment, and the exact repair-system, resin, and curing-lamp instructions still apply. Stop when a replacement condition is present, then measure and document the complete line before choosing the next action.
5. Can edge or driver-view damage be repaired?
Edge and driver-view damage needs a stricter location assessment, not an automatic repair. When a crack intersects more than one edge, or a DPVA condition in 002-2022 is exceeded, that edition recommends replacement; other edge damage still requires judgment. Do not assume a small mark is harmless near a sensor, display, coating, or camera-related area. Map the wiper sweep and vehicle features, check applicable law and OEM information, and refer or replace when visibility or operation may be affected.
6. How does contamination affect windshield repair?
Contamination can prevent resin from filling the break cleanly and can leave an unacceptable optical result. When water, dirt, road film, washer fluid, or another visible impurity is present, inspect and remove it only by the approved process. However, 002-2022 lists visible contamination that cannot be removed through cleaning as a replacement condition. Do not hide the residue with more resin; document the condition and replace or refer the windshield if cleaning does not restore an assessable break.
7. How does resin injection fill a windshield break?
Resin repair removes or displaces air and fills the break with a curable material intended for the repair system. When the damage passes the repair decision, use the exact injector or air-removal method and compatible resin instructions; do not invent pressure, cycles, access work, or fill settings. The visible SuperPDR system record shows only a high-level inspection, drying, resin, penetration-check, UV, and finishing order. Confirm the supplied manual and stop if the fill cannot be verified.
8. How long should UV curing take?
UV curing time must come from the exact resin and lamp instructions, not from a general FAQ or another product record. When the specified resin, lamp, distance, and environment are known, follow that matched procedure, but do not transfer a time or setting between systems. Stop if the resin identity, lamp instructions, or curing condition is uncertain. Check the current documents, complete the specified cure, and inspect the fill and surface before accepting the repair.
9. Will a windshield repair become invisible?
A completed repair can improve clarity without becoming invisible. When applying the ROLAGS inspection method, view from the driver's position and an oblique outside angle; a cosmetic blemish may remain even if the void is filled and the surface is flush. However, significant light scatter, contamination, air pockets, open leg tips, wiper interference, or a possible effect on vehicle operation is not merely cosmetic. Inspect against more than one background, document the result, and replace or escalate if acceptance fails.
10. What damage means the windshield should be replaced?
Replacement is the correct next action when a binding rule or the applicable 002-2022 limitation rejects the damage. Examples include both lites penetrated, inside-lite damage, unremovable contamination, interlayer damage or discoloration, a stress crack, specified edge or DPVA conditions, certain multiple-long-crack patterns, and conflicts with value-added features. Do not continue when exact system instructions are missing or final inspection fails. Confirm the condition, document the stop decision, and use the PDR Tool Buying FAQ when equipment evidence is also unresolved.
