I've dropped plenty a bammies in the water,and if the rods finish is intact,there'll be none getting into the bamboo.If it's not in good shape I'd suggest stripping and refinishing the entire rod,this needs done periodically anyway,unless the rod has been "impregnated", which puts the finish throughout the entire blank.

"I've often wondered why it is that so many anglers spend so much money on,and pay so much attention to.the details on the wrong end of the fly line.If they took as much care in selecting or tying their flies as they did in the selection of the reel and rod,They might be able to gain the real extra edge that makes it possible to fool a fish that has,in fact,seen it all before" A.K.Best
