1. Determine the extent of the scratch
When a small scratch appears on the bus glass, the first thing to do is to determine the extent of the scratch. If the scratch is shallow and is only a slight scratch on the surface, it may be solved by a simple repair method. But if the scratch is deep and even affects the strength and safety of the glass, you need to consider replacing the glass. You can touch the scratch gently with your fingers to feel its depth and roughness, or observe the scratch at different lighting angles to better judge its severity.
2. Choose repair tools
For shallow small scratches, you can choose some special glass repair tools. Common ones are glass repair agent and abrasive paste. Glass repair agent is usually a liquid chemical that can fill the scratch and make it less noticeable. Abrasive paste can remove the uneven part of the scratched surface through a slight abrasive action. When choosing repair tools, pay attention to choosing products with reliable quality and suitable for bus glass materials. At the same time, you can also prepare some clean soft cloths, sponges and other auxiliary tools.
3. Repair steps
When using glass repair agent for repair, first clean the glass surface to ensure that there is no dust and impurities. Then apply the repair agent evenly to the scratch, and wait for a certain period of time according to the product instructions to allow the repair agent to fully penetrate and solidify. Finally, wipe it clean with a clean soft cloth. If you use abrasive paste, apply an appropriate amount of abrasive paste on the sponge, and then grind the scratch in a gentle circular motion. Be careful not to use too much force to avoid causing greater damage. After grinding for a period of time, rinse the glass surface with clean water and check whether the scratch has improved. If necessary, you can repeat the grinding operation until the scratch becomes less obvious.
4. Precautions
When repairing bus glass scratches, pay attention to safety. If you need to repair it on a moving bus, make sure that it will not affect the driver's vision and driving safety. At the same time, the repaired glass may be reduced in strength and performance. Closely observe the situation of the repaired part and deal with it in time if there is any abnormality. In addition, for more serious scratches, do not repair blindly. It is best to consult a professional car repairer or glass manufacturer to determine the best solution. In short, when repairing bus glass scratches, be cautious to ensure the repair effect and safety.
