Ive use these glue sheets on three bats now... two new applications and once, to migrate rubbers from a cracked blade to a new one. They are easy to use and provide an nearly instant attachment for the rubber.
Peel and stick to the blade, trim around the edges. Peel the second liner and affix the rubber. Trim the rubber.
Repeat the process for the opposite side... and then "press" the finished product on a nice flat countertop under some books for a while overnight works well but not necessary if you dont have the convenience of time.
Apply the edge tape of your choice and youre off and running.
