'Re-furbishing' a drumset

[Perishz]

I was chatting with a drummer from a pub and he told me this would be gd to do for a new set of drums.

Things like :-

-Strengthening the shell
-oiling hardware parts to prevent rusting of any sort
-oiling/lacquering the inner shell of the drum to prevent mites/bugs

would like know more about this 'Process' so-to call it.
