Cut the tail bone out and get all the meat and fat off. You should still have enough skin left to hold it together. Like the others said, give it a good washing - I use Fantastic on the feather shafts to help degrease and then wash with Pert shampoo and blow dry. Should work fine. After it dries good, I bondo mine, I've also used hot glue, but it didn't work as good as bondo.
