I use this stuff to polish plastic, metal, paint, etc.. I think it's just white clay suspended in liquid. It makes things shiny and doesn't cost as much as the other stuff. There may be better products on the market, but I wouldn't know since this has suited my needs for the past 15 years in terms of turning yellow headlamps back to clear or taking swirl marks out of paint jobs. It will take away lacquer paint though, so don't get too crazy.
