Bar's stop leack actually plugs the heater core rendering it useless.

GM has a cooling system sealer they use in new cars, don't know the part number but it come in a large pill with six or so on a card. Dealer will have it in the parts department, five bucks or so. Works pretty good and if they use it one warranty repairs, it must be ok. Worth a try.
