I live in Phoenix, AZ and I don't know if you're aware, it gets a little warm in these parts. I have some outdoor speakers on my patio and the metal screens have popped off. I noticed there were some dabs of glue/silicon at edges. I'm guessing the glue couldn't handle the heat. Anybody have a good recommendation on what to use to keep the screens in place in the desert heat? They are shaded year round. TIA
