Why would it require new rings if you pull the jug? I usually start with fairly rough sand paper. Spray some WD-40 on the glass (or other flat surface), and lay the wet and dry sand paper on the glass. The WD will help the paper stick to the glass. And it gives the metal a nicer finish. Then move the head (or jug) in a figure 8 pattern using with hands. If you just go back and forth, it is easy to rock the piece a bit, making the edges higher. I did one with very fine paper, only to find out that the gasket doesn't want to stick to something so smooth. Def don't go finer than 400. Maybe even coarser. If you think this takes to long, remember-if you don't have the time to do it right, how do you have the time to do it twice?
