What adhesive did you use and did you do anything to “cure” it?
In my shop I use the black Tesa tape whether it’s pre-cut for a specific device or I use the rolls of adhesive. I’ll heat the device up with a heat gun and then use a few small Irwin Quick Grip clamps to apply pressure and it works really well. Also when you apply the adhesive, make sure you don’t touch it. The oils from your skin can have a negative affect on the adhesive. You can also try 3m adhesive promoter. But WHATEVER you do, for the love of God, DO NOT USE SUPER GLUE.
