I tried to do it. And I stress, I tried to do it. In my case, I just made a big mess more than anything. After reading the instructions and several "how to" books, I realized that it takes several minutes to an hour to get out what ever haze, scratches or oxidation that you have. Keep it wet and I recomend that use an angle die grinder rather than your drill. It's easier to handle. The kit comes with the silicate powder (or something like that) and the buffing pad with the adapter. Not too expensive. At the end I just ordered new glass.
