Before my pro shop sold to a different owner, he had an OLD Lustre King that he kept up and used a polishing compound. Most of the machines you see these days just use a wax block. It will make your equipment shiny, and basically worthless. A reactive ball is useful because it is porous so it grabs the friction faster for a more angular break point, more angle usually means more strike potential. The wax clogs the pores. So if you have urethane or plastic, lustre king away...otherwise be careful.
