Review on CS-4300 Mirror Adhesive: Safe, Easy to Use Cartridge for Mirrors - 10.1oz by John Murphy

I have followed the instructions. I used it on a broken 1998 driver's side mirror and replaced it with an OEM part. When I removed the broken glass, I noticed a sticky light brown glue that was still wet after so many years. I thought whatever it was, it was an amazing product. For a long time I could not find what I need - Mirror Mastic. My friend who works on boats told me what to buy. I still had to put a piece of wood in front of the mirror to hold it in place while still taped everything in place as you need to let the product dry for at least 24 hours. Otherwise, the mirror will fall to the ground and break. Once it cures it will hold it in place just like the original. Good product.
