Hey Mike,
Can one over do the sealant. When my rad was replaced a few thou ago I'm not sure if the GM tech put the sealant in?? Would it hurt for me to add the Bar's Leak??

It won't hurt anything to add the supplement, but you will lose a little coolant in the process. Just be sure to use distilled water and whichever coolant your car needs. If I was you, I'd get 2 tubes of the powder stuff and dump it in the upper hose. You'll make less mess that way. You can drain the radiator via the drain valve at the bottom, just enough to empty the upper hose. That way, you don't have to clean up a bunch of coolant from the floor. Once the hose is empty, shut the valve, take off one end of the upper hose, dump the stuff in, put it back on, refill system. Voila! Properly supplementized system and peace of mind for little cost.
Let us know what you do and how it turns out...
