Baking soda and crazy glue ...

Use masking tape to tape off one side of the hole. Using something like a small screwdriver, scoop a TINY bit of baking sode into the hole then squirt in enough crazy glue to visibly wet the baking soda. Continue this till the hole is filled. Do this with each hole. Remove the masking tape, file or sand the holes level. Redrill and away you go.

Baking soda and crazy glue create a chemical reaction and will smoke slightly during the process.

In my opinion this stuff beats any other product - epoxy or otherwise - because the thin viscosity of the crazy glue allows it to seep into every minute crack and crevice, unlike thick epoxies or JB Weld.
