On that dimple Jim....You can try to re-fill that tiny area as the plastic cools OR you can wait until it is shrinking in and put a few drops just on the end area, not worrying about overfilling. In fact, be sure to overfill just a bit but only on the very end.
Then, before removing the bait, but after it cools well, take a razor blade and slice the excess off even with the mold cavity. Viola...no dimple!!!
This works great but is a pain to do on all the baits. I only do it on the ones that I send to a couple of very particular customers. The rest go with a small dimple.
