This expensive glue is terrible, I followed the instructions exactly and took my time, but it did not hold and just made a mess where I attempted the repair.
Works well on plastic kayaks to repair holes, bond pieces, and do some customization.
Mixing is easy as using toothpaste. Very quick to mix and become usable.
Hardens fairly quick depending on the temperature.
Can sand it to shape after it dries.
Make sure to grind your aluminum down to a clean bright surface with stain less steel brush and put in some backing cloth on bigger holes.
