When I was in my first serious Design class at the Cleveland Institute of Art, I was warned by the instructor that if I built something it had better be constructed well. My first project was a hat that I constructed out of sheet acrylic, a hat with windows.
That acrylic was not easy to work with. Cutting was fine, but gluing it together was a nightmare. I tried EVERYTHING. Superglue (cyanoacrylate), silicone caulk, epoxy - any and everything that could glue acrylic.
I finally had it assembled. It was decorative, so there were small pieces as well as the larger structure. I was proud, but concerned, with good reason. As I walked up to make my presentation, smaller pieces started falling of. The larger structure held, but it was pretty much a disaster. At least is wasn't as much of a disaster as the student that squeezed toothpaste all over a motorcycle helmet for his project.
Oh if Only I knew about E6000 back then. Since I have graduated I have been a product designer. I have actually attended several seminars on various adhesives, their composition and their abilities. It wasn't until I started crafting again, until I found E6000.
If you haven't tried E6000, you don't know what you're missing. For crafting, it is the greatest stuff. It can take up to 3 days to dry completely, but when it does, WOW. It adheres to almost anything, metal bales to metal bezel cups? No Problem!
Read the reviews at Epinions for E6000 if you don't believe me. This stuff is beyond great!
