What kind of glue is used to repair cracked car taillights?
2 Answers
AB glue can be used to temporarily repair cracks in car taillights. Additional information: Maintain good sealing during repair: Especially prevent contamination and damage to the reflector coating. When replacing bulbs or diffuser glass, avoid touching the mirror surface with fingers to prevent sweat or oil marks from causing the reflector to lose its luster and reduce reflection efficiency. Car lens treatment: If there is dust on the reflector, it can be blown clean with compressed air. For stains, use a cleaning cotton swab dipped in hot water to gently clean. The diffuser glass should be correctly installed as specified to prevent loosening and displacement, keeping the prism vertical. Regular inspection: Generally, there are positioning devices or left/right markings on the glass. Regularly check and adjust the headlight beam to ensure the headlight's irradiation distance meets requirements, with both beams aligned vertically.
The car's taillight has a crack, and I used epoxy adhesive to fix it. This stuff is super reliable. Last time my taillight cracked, rainwater seeped in and nearly burned out the bulb, so I quickly searched online. Epoxy adhesive comes in two parts (A and B), and after mixing and applying, it can withstand high temperatures and is waterproof, unlike regular tape which doesn't last long. When applying, first clean the crack surface with alcohol to remove any grease or dust, then apply the adhesive evenly, press the crack tightly, and wait 24 hours for it to fully cure. After using it once, I had no issues for over a year, but remember to choose automotive-grade epoxy—don’t cheap out and use hot glue. Silicone adhesive is also good, but I think epoxy bonds more firmly, especially for DIYers like me.
