For all of the naysayers.

How about this one? Try some scotch tape.

Clean the hook and make sure there is no oil. Apply, one, or two layers. Rarely will it take more than that. Then a small spot of grease on the tape.

This is good for a couple of rounds of skeet or a round of sporting clays.

This is also a good way to determine how thick the metal shim you will use for a permanent repair needs to be.
