i actually prefer it to toe guards. application wise i would do the following:
1) use masking tape to mask the face/back of your bat, to prevent dripping during application
2) i apply a blob on the center of the toe, wet my finger and spread it evenly. thickness is really up to you, but as thick as a toe guard works.
3) let dry for at least 24 hours or it can come off.
4) make sure to do it outside/garage - as the stuff stinks.
also i've got the clear goo - so it looks alot better then the black one - but that is purely cosmetic.
