A broken taillight cover can be repaired using glue and plastic. Here are some maintenance precautions for car headlights: 1. Replacement: Car headlights must maintain good sealing, especially to prevent contamination and damage to the reflector coating. When replacing bulbs and diffuser glass, avoid touching the mirror surface with fingers to prevent leaving sweat or oil marks that could cause the reflector to lose its luster and reduce reflective efficiency. 2. Regular inspection: Regularly check and adjust the headlight beams to ensure the headlight's illumination distance meets requirements and that the high and low beams are aligned. The diffuser glass should be correctly installed as specified to prevent loosening or displacement and to maintain the vertical alignment of the prisms.
Last time my headlight cover got cracked by a flying stone, I tried hot melt glue but it really didn't work—it turned white and brittle under the sun. After researching, I found that most modern headlight covers are made of PC plastic, so you need to use modified acrylic adhesives like ergo5920 or 3M structural adhesive. Never use regular super glue (502), as it will corrode the plastic and make it worse! For small cracks, it's best to clean the fragments thoroughly, apply adhesive to both sides, press them together, then sand and polish with fine sandpaper after hardening. Finally, use a restoration agent to make it more transparent. If the hole is too big, just get a used replacement part—it's the most hassle-free solution.
