I bought a used 996T and the previous owner had taken off the case and used a din sleeve (which he lost) and the case got scratched up. I am adding a "discriminator" (they do not have a real discriminator but a quadrature detector) for testing and looking at interference, distortion (a lot of amateur radio repeaters have terrible audio). Since the case is already off, I am going to paint it. I saw the Rust-oleum hammer finish paint at Walmart. Going to use plastic media as it will not excessively eat the metal up. I wish DuPont sill made their High Build vinyl paint, used in the early 70's to simulate a vinyl roof, as it is a thicker, more resistant to scratching, but it is gone. Zolatone also has a nice texture, but expensive.
That is what I was going to use to refinish a CentraCom console to replace the white vinyl ends.
