After the Helpful thread on gluing thumb inserts...How about the finger inserts?....The trouble I have when I use a large reverse pitch is keeping the back of the insert level with the rim of the hole....when installing normal inserts I can push the back down & then Glue it.....When using Vacu inserts where you only glue the front part I have trouble getting a neat installation...I usually trim the excess with a razor....any tips on vacu inserts would be appreciated.
