Currently I use tape. But Poochy does it the way lots of people do. I recommend pooches way of doing it. If you happen you use tape be sure to dremal down the edges of those slots that tape goes thru. Other wise it will cut the tape and cause your batter to move. It could move in to the belt and cut the casing(mine did it) or just fall out of the car.
Just some advice. Hope it helps.
