Polishing Bakelite
#3

There are different formulations of Bakelite. These variations make it sensitive to UV, alkali, to the type filler, size of filler and amount of filler.

The most important caution in re-surfacing Bakelite is be aware when filler is reached. By molding technique, the filler migrates away from the surfaces leave the opaque resin on top. Sand through the resin and reach the filler/resin, no polish will help at that point. The solution is to use an opaque toning lacquer, at that time the desired tone can be used or a lacquer solid color paint.

The same model radio can be expected to polish in the same manner, but another model/brand may react differently, such as have filler very close to the surface.
