Scheme 22
Before repairing damage point, please be sure to always observe the following information
- A workplace without UV radiation should be available, otherwise it can result in paint adhesion problems of the filler resin or finish resin.
- The windshield temperature must be between 10°C and 25°C to repair the stone marks; if applicable, heat or cool down windshield with suitable methods. Otherwise it can result in paint adhesion problems of the filler resin or finish resin.
- Only damage on the outside window surface may be repaired.
- Damages to the inside of the windshield or to the plastic laminate are not permitted.
- Ensure that moisture has not penetrated into the damaged point (seal damage point immediately after damage using adhesive tape and repair it as soon as possible).
- The diameter of the chip should not exceeded 5 mm.
- Any radial cracks extending from the damage point should not exceed 50 mm. They should not end at the rubber window seal and never reach to the outer edge of the window.
- This repair method can be used only when the damaged point is outside the driver's long-range field of vision. After repair, a spot of approx. 2 mm in diameter can still be seen.

- Position windshield (1) on body flange and press on until it makes contact with spacers. Then fix in place with suitable adhesive tape. The curing time is approx. 2 h measured from the time the windshield (1) is installed. The rated accident strength is achieved only after approx. 8 h.
Scheme 33
- Check damaged point for moisture If applicable, heat damaged point with hot air gun and allow to flash off for approx. 10 minutes.
- Clean windshield around damaged point with cleaning agent (12).
- Evaluate damaged point A conical fissure or filling cavity should be present in each damaged point to ensure that the filler resin (8) continues to flow.
- If applicable, crack damaged point to create conical fissure or filling cavity. Use stone impact cracker (5).
- Install inspection mirror (3) on inside of windshield.
- Chamfer edges of damaged point using milling cutter (4). Roughen surfaces and remove grayness from porous surfaces.
- Blow out loose glass particles and wipe out with paper towel. Do not use compressed air when blowing out to prevent enlargement of the damaged point.

- Place tool holder (1) on windshield so that it is not in the area of the damaged point.
- Press suction cup of tool holder (1) onto windshield with clamping lever (2) in vertical position. To improve adhesion of suction cup moisten with thin layer of adhesion gel (13).
- Arrest tool holder (1) on windshield by moving clamping lever (2) down.
- Screw injector (10) into tool holder (1) until rubber nozzle (10.1) makes slight contact to windshield.
- Mark cracks extending from end of damaged point using suitable pen to check whether cracks have become longer.
- Remove tool holder (1) and position so that rubber nozzle (10.1) of injector (10) is located at center of damaged point.
- Arrest tool holder (1) on windshield by moving clamping lever (2) down. If the cracks extending from the damaged point increase, immediately reduce pressure by unscrewing injector (10) from tool holder (1) to prevent the windshield from breaking.
- Screw injector (10) into tool holder (1) until rubber nozzle (10.1) on injector (10) makes contact with windshield all-round. The contact pressure is indicated in the inspection mirror (3) by the edge of the rubber nozzle (10.1) becoming a darker red or deforming edge (10.1).
- Completely unscrew injector piston (10.3), moisten piston thread (10.4) with a drop of filler resin (8) and fill 12 drops of filler resin into the filler opening (10.2). When reusing new injector (10).
- Completely unscrew injector piston (10.3) and fill three to five drops of filler resin into filler opening (10.2) When reusing used injector (10).
- Provide for sufficient pressure by screwing in injector piston (10.3) (picture B). Observe deformation of rubber nozzle (10.1) of injector (10) to achieve good repair results. The opening is widened (picture B) if sufficient pressure is present. The pressure should not be present more than 90 s.
- Hold injector (10) to prevent unscrewing from tool holder (1) and provide for vacuum by unscrewing injector piston (10.3) up to the thread end (picture A). Observe deformation of rubber nozzle (10.1) to achieve good repair results. The opening is smaller (picture A) if sufficient vacuum is present. Do not remove injector piston (10.3) beyond end of thread to ensure that vacuum is maintained. The thread end is indicated by a cracking noise when unscrewing. Maintain vacuum at least as long as pressure. The longer the better.
- Increase contact pressure of injector (10) on windshield by screwing injector (10) into tool holder (1). Observe damaged points coming from cracks to prevent additional damage.
- Repeat steps 11 to 13 (8 to 12 times). Increase time of pressure 50% for each repetition. The air is completely removed, when air pockets are no longer visible under vacuum after an additional waiting time. Air not completely removed can be recognized as small black spots. Perfect repair does not have black spots. Otherwise, repeat until air pockets are no longer visible.
- Check results by holding white background behind. If the repair results are not satisfactory, repeat steps 11 to 15 by maintaining longer pressure and vacuum (2 to 5 minutes) until air pockets are no longer visible.
- Cut off an approx. 2 to 3 cm strip of curing foil (11) with bow-shaped blade (7).
- Loosen clamping lever (2) and pivot tool holder (1) to side using injector (10). As long as the filler resin (8) is not yet cured, it is possible to continue work at any time.
- Slightly wipe out filler resin (8) in damaged point using lint-free cloth.
- Apply a drop of filler resin (9) at top of damaged point and attach prepared strip of curing foil (11) first at bottom of mark and lay over area of impact. Avoid formation of air pockets. Do not press curing foil (11) down; this could endanger the repair result. If applicable, repeat operation.
- Remove injector (10) from tool holder (1) and screw in injector piston (10.3) one thread.
- Store injector (10) in opaque bag to prevent filler resin (8) from curing. Storing filler resin (8) and injector (10) at 4°C to 8°C in a refrigerator prolongs applicability significantly.
- Position UV curing lamp (6) above area of impact, switch on and allow filler resin (9) to cure for at least 5 minutes.
- Switch on UV curing lamp (6) and remove.
Scheme 37
- Remove curing foil (11).
- Scrape off cured finish resin (9) on windshield using bow-shaped blade (7). To achieve good repair results, move bow-shaped blade (7) at an angle of exactly 90° to windshield by weaving crosswise above damaged point. Scraped finish resin (9) is visible as mat or gray surface. Shining resin surfaces are located deeper and not yet sufficiently filled and must be treated with finish resin (9).
- Apply a drop of finish resin (14) to scraped finish resin surface and polish to transparent finish using polishing cloth from repair kit. To achieve good repair results, a small quantity of dry finish polish (14) should already be present on the polishing cloth. The final result is a shining transparent point, similar to a dried rain drop.
- Clean repair surfaces using cleaning agent (12).
