So proud of myself but...
I should have known it wouldn't be that easy. I pealed off some of the sealant and pumped it up again, it slowly bubbles off. I as I was going inside to look up how much replacement is, I noticed two puddles on the floor, one clear and probably off the extra overflow tube, but the other on closer insepection show coolant all over the oil pan. I don't see anything around the water pump but so I am hoping it's a radiator hose hose or transmission line or something. I am fearing a cracked block. Wish me luck on that.
