The briar is dead, can't feed it. The product you mention is not a pure wax. Check the ingredients. If you wish to wax and shine your pipe, it is not a once and done procedure. Pure bee's wax is suggested because it adds nothing to the wood. The was is not simply a coating if properly applied. It fills the pores in the wood. There will be a bit of a wax coating, too much means you didn't buff well enough.
My suggestion, since you are apparently unwilling to accept the conventional wisdom from people representing probably 200+ aggregate years of smoking and pipe care, is to lacquer the darn thing up, put it on a shelf, sit back and admire it as you smoke a cob or something.
