Perfect for bonding aluminum when welding/brazing isn't an option
This stuff really does contain aluminum! I used it for a client project that needed to be electroplated, and the metal components could be welded or otherwise soldered together, so I used this stuff and voila! Super strong bond and no electroplating trouble at all!

Works great!
Works great! I had a hole in a high side AC line on a Chrysler Pacifica. After repair the system is sealed and holds pressure.

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. Edit- after a few years of having this hold my bumper and handle covers to my car- I totaled my vehicle by hitting a deer. The bumper flew off into the road and the cover stayed on! This stuff sure does have a strong hold.

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.
