Shocked this holds up so well!
Used it to adhere bumper cover, and door handle covers to my car as I was blacking them out. It's held up for over 6 months through the heat, cold, rain, and wind. I do occasionally hear a bit of cracking when it's really cold but it's still on there.

Defective product!!!
After trying this product per instructions, it never cured. I then tried to increase the ratio of hardner by about 25 percent. It still did not harden. I would recommend trying this on a sample before working on the intended repair. Using this on the intended repair resulted in scrapping a very expensive air conditioner coil.

broken / damaged tube
The intent was to repair my AC.When opened the packet I see a damaged product that cannot be used because the packing is broken I don't want to take chances on a product that has air contact or exposed because it must have already compromised it's quality already. Asking for refund and ready to ship it back as the way it arrived.
