I have worked with this company before and with other types of adhesives, such as epoxy for metals from other companies (which are also suitable for use in high temperatures, for metals exposed to seawater, etc.). At first, the catalyst did not come out (while the adhesive was coming out fine), and then it wouldn't stop coming out. I glued aluminum to galvanized sheet metal at 12:30 noon, and it was still very tight like gum until 2:30 in the afternoon. What does it mean by 45 minutes?

After a few hours, around 10 pm, I removed the clamps. The materials had bonded, but it hadn't fully dried. I easily scraped it off with a sharp knife. I wouldn't trust it for gears that are supposed to be glued. I expected it to be more difficult to remove once it dried, more like cement, as I know from other adhesives.

SOS: It hasn't even been 24 hours and with the first slight force, I heard a "crack" in one of the bonds. It opened up for no reason! Look at how much adhesive I had applied in the attachment.

I had a small hole (about the size of a pen tip, smaller than a screw) in the metal near the thermostat in my car... I cleaned/wiped the area, lightly sanded it with the sandpaper that came with the package to create a suitable surface, and then applied the mixed adhesive as the instructions say... And I waited for 45 minutes ++, as it says...

I should note that I had emptied the coolant beforehand to avoid getting the adhesive wet, and I worked on the engine for a very short amount of time, always being careful not to exceed the usual 90 degrees at which the fan normally turns on... Then I turned off the engine and let the adhesive cure as it said, meaning that heat accelerates the curing process... After about 5 hours in total, the result looked very good, the adhesive became like a solid body, like a bone, I don't know how to describe it... It tightened a lot... And of course, there was no leakage after I added the coolant again... I should also mention that this is a temporary fix to give me time to think about what to do, but also to be able to drive for a while... It was a bit disappointing at first until it dried, but in the end, it was okay... Let's see how long it will hold, until I find a proper and permanent solution... I hope it gives me some time... That's it... I'm thinking of applying another coat tomorrow for extra security... It also needs 24 hours to fully cure, it says... We'll see...

I should also mention that if it gets on your hands, it cleans relatively easily... It comes with a little container with a plastic side for mixing... And a cap to close the nozzle and prevent air from getting in... It doesn't have a strong smell, but it doesn't smell very nice either, but in terms of durability, these are just details... Overall, I'm satisfied... It saved me temporarily...
