Not to hijack the thread, but I don't think this is a good idea. There are lots of coatings made for this purpose, and fiberglass atop metal is going to trap any moisture that gets inside, and your panel will then rust from the inside out, out of sight and with no way to know it is happening until you see the rust bubbles. Any flex will tend to crack the thin glass coating, then any surface moisture can wick and be trapped. Just my $0.02 on the method. How about lizard skin or a good paint?
