I dont see why you couldnt seal them off, would probably be easier to just "enhance" the drain system of the rockers and coat them in a ton of some sort of rust encapsulation. I even joked around with a buddy of mine about making a little door in the front of both of them so that you could get a hose in there and really clean it out good. Just buy an extra set of rockers, putting new ones in every 30 years isnt that bad is it?
