Glass refinishing/buffing

hey guys my side windows are not in totaly bad shape. they are original and have slight scratches from being rolled up and down so many times over the years. I've heard of doing this but want to make sure i won't ruin my windows. also what is the best way to go about "buffing" the scratches out. Can you just wet sand the windows with say 1600-2000 and then buff them as you would paint? thanks
