Hello, I would like some advice on what material/epoxy/resin to use to repair a 2" diameter hole in the shell of a phenolic-shelled Pearl President tom.

I envision cutting a piece of plastic or other material to fit inside the hole and then patch it together and refinish the outside in kind.

Also, is there a good fix for a cracked kick drum and floor tom?...they were damaged during shipment to me from across the country.
