No, that in my opinion would be an overkill. So not worth the trouble, (otherwise this project will never get done) - Besides I'm not interested in picking up conversations taking place in Antarctica. Just interested in knowing what people a few hundred feet away are talking about... Therefore steel covered with epoxy paint (as rust proofing) will be good enough for this project. I would have gone for plastic, but this was available in the right size and shape. And since it's steel, it's mostly immune to vandalism, like kids throwing rocks at it for example, (which I know they will at some point in the future). Also I can weld on the brackets and other stuff, as it's steel after all. So very easy for me to work on. I mean it's a wok, so by design it's already pretty robust piece of cookware. I'll just convert it into a parabolic mic.
