Yep. Glue on metal. There were a couple of air bubles that formed but since the glue took 24 hours to cure.... and the fact that I am impatient. I was able to smooth them out. You can see inthe corner where the cover got nicked and broke off.
I am getting ready to do another one but this time in leather. I am making a scouting trip to the Goodwill store to find a donor jacket to provide a piece of leather that will work. I'll post my results when I get there.
