doesn't stick well, after a few days the very lightweight soundproof foam pieces fell off. the application was done on sheet metal, obviously clean and dry.

I got it for soundproofing panels, whether on the wall, the ceiling, or any material I stuck them on, it holds perfectly... There are panels with glue already on the back... stay away! Double the cost for nothing and they fall off like feathers... whereas with this glue, you pull them and they don't come off! Just use it correctly as indicated on the packaging... mix for 2 minutes, spray the surface and the material, wait 1 minute and place it! In 2 minutes, try pulling it... If I use it for other purposes, I'll update, but for soundproofing panels it's perfect! Be very careful... as soon as you finish using the spray, if there's any left and you want to store it, turn the spray upside down and spray for 5 seconds to release air so it doesn't stick to the cap!

I bought it to stick the bottom part of the base that came off over the years from the bucket of the construction cart, but it didn't stick. Maybe I didn't stick it properly, but in the end, I can't avoid using welding.

The glue is really strong, its price is good and it seems to be durable. The downside is that the plastic cap of the spray is of poor quality, resulting in it breaking with the second use and having to remove the liquid from inside with a toothpick, where afterwards it took a while for the glue to come off my hands.

In conclusion, it is highly effective, but during use, be careful and definitely wear gloves.

I bought it to glue fabric (not leather) on wood and you need gloves, no matter what you do with the glue. Don't expect it to spray like a paint spray, it requires attention and reading the instructions when you finish something if you want to store it later. Basically, it's decent and there aren't many things that they sell you at this price. You will have better results when there is no heatwave but in a cool place
