I have a fox skull that is already euro mounted, problem is, it fell off of the wall and the lower left jaw broke in half and came off. I tried super glue, but with no luck. The left over marrow on the inside of the jaw is too porous. What type of bondo or glue should I use to reattatch it but won't spread everywhere and make it look glued?

Two part epoxy. Wipe excess with lacquer thinner.
