I have no practicle knowledge of BUDs, but shouldn't you be able to use any metal material with holes 1/4" or smaller, or even solid? As long as you keep the same curve as the original shape, I wouldn't have thought it would matter.
can we say duct tape? It looks metallic and probably has some metal in it, i would try that first, otherwise what part of the country are you in, there is a c band dish sitting on hiway 11E between knoxville and morristown tn in front of lakeway disposal's building. The sad thing is it will probably end up in the dump, or be recycled for the aluminum, I wish I had my pickup truck with me, i would pick it up
