### ⭐ Heated backlight terminal failure.
*by A***R on June 23, 2025*

I used this to replace an electrical tab that had snapped. This adhesive held the tab well, but only conducted enough current to clear the window a few times. Tested and found the resistance of the joint had increased. *** Instead, use an epoxy with a significant silver content. These are expensive! ***

### ⭐⭐⭐⭐⭐ Proper technique is important.
*by R***N on May 20, 2021*

This adhesive requires close contact between the tab and surface, the adhesive does not bridge well. If it fails you most likely didn't get a close contact or you moved it while it was curing. Prep is important, clean the surfaces with acetone or alcohol. Practice your technique for attaching and holding for a few minutes. You will need good technique holding it in place while it cures.
