Remember that the glossy layer in Bakelite is thin. If you get too aggressive with abrasives, it's possible to polish all the way through it, and then you are down into the pulpy under-layer which no magic potion or process will polish to a shine.
Some Bakelite cabinets will polish up nicely, and others are just too weathered (or whatever-ed). This comes up all the time in the radio collecting world. You can spray on clear coat to make a weathered cabinet shiny. Some people also use wax, but I consider that a temporary solution.
