What kind of adhesive is more suitable for car door sealing strips?
2 Answers
Car door sealing strips can be adhered more appropriately using 502 glue or silicone sealant. The detachment of car door sealing strips is mostly caused by aging, so regular maintenance should be observed. Pay attention to the force when opening and closing the car door, and avoid excessive force, which can easily cause damage to the sealing strips. After driving in the rain or washing the car, the moisture in the door gaps should be wiped dry to prevent acidic rainwater or detergent residues from corroding the sealing strips. If aging or cracking of the sealing strips is found, they should be replaced promptly. Dangers of sealing strip detachment: Blockage of drainage holes: After installing sealing strips, some drainage holes may be covered, preventing rainwater from draining out during rain, which can lead to rusting of the door metal and even water leakage into the car; Aging of adhesive tape: If the adhesive is not strong enough, the sealing strips may detach after some time of use, and may even stick to the car's paint; Affects aesthetics; Sound insulation effect is not obvious. Precautions: Car sealing strips should be checked from time to time for cracks, especially for any broken areas, and should be repaired in time to prevent heavy rain leakage. You can purchase special adhesive for car sealing strips to stick them back. If the damaged area is too large to repair, then professional maintenance personnel should be consulted to handle it.
I previously had a loose door seal and tried using regular double-sided tape, but it wasn't durable—it fell off after just a few days of wind and rain. Later, a friend recommended automotive-specific adhesive, like 3M double-sided tape or silicone-based glue, which has super strong adhesion, is waterproof, heat-resistant, and can accommodate the elasticity of the seal. The process is quite simple: first, clean the contact surfaces of the door edge and the seal, removing any oil or dust; apply the adhesive in a thin, even layer, wait until it's semi-dry, then press firmly to bond. Remember not to use fast-drying glue like super glue (502), as it can corrode plastic seals and cause cracking. I applied it last month, and it's still holding strong without any loosening. Regular maintenance can also involve checking if the seal is aging—early upkeep can prevent leaks and noise.
