If you have to use glue, you can only choose waterproof and anti-aging adhesives, such as all-purpose glue. However, it may stick the paint off the adhesive parts.

If it is rubber, it can be glued with HY-308, which is stronger.

If the automobile adhesive tape is stuck, just use YH-8 18 to remove it. The special rubber adhesive can not be torn off after being pasted, and the rubber can reach the breaking strength.

At present, when automobile maintenance enterprises repair damaged plastic bumpers, they all directly use welding plastic guns to heat and dissolve the plastic-coated covered electrode at the damaged parts for repair, which can't really be repaired. Glue is not recommended.

It doesn't usually stick. See how it's buckled. If it doesn't work, replace the bumper.
