This stuff means business. I used to to join metal to metal after tearing apart a monitor for a raspberry pi magic mirror project. Follow the simple instructions and you will be good to go. I suggest not wearing clothing you don't want to damage if you tend to be sloppy. Once you mix the 1:1 solution, there is no going back. I used a popsicle stick to mix the two, then carefully used the popsicle stick to apply the mixed epoxy. Very happy with this product.
