Epoxy will become brittle over time.

I used this paste to repair the window defroster cable that detached from the rear window of my Jeep. The key to using this product is preparation since the potting time is really short so you must prepare the surface correctly. I taped off my Jeep window and left out the area where the cable make the contact. I mixed the epoxy thoroughly as in the instruction and squeezed out onto a cardboard. I used wooden coffee stirrer and applied the epoxy paste on the glass, taped defroster cable to the window and secured for 24 hours with tape. The defroster worked again afterward. My only criticism is the epoxy will get brittle with time. Mine lasted for about just over two years and the cracks in the epoxy created too high resistance for the defroster to work efficiently. I am ordering this product again to repair the cracked epoxy. This is why I only give it four stars.
