Randall, there is a product that used to be available for fixing "holy" motorcycle gas tanks called "KREEM". I can't see why that wouldn't work on a coolant reservoir if you wanted to go ahead and prevent the problem by pre-lining the reservoir - could save on the replacement part cost. Of course, just as much work to drain and get the tank out of there... but it appears you may have a thrifty side that can appreciate the part cost savings.
