I would clean it off with some hot soapy water and garden hose if possible and make sure that is where the leak is coming from (it does look like a typical radiator leak but you never know). I would not add any kind of stop leak to the system. Keep it toped off and check the leak every day you should be fine. Don't let someone else drive it or it will go catastrophic for sure. Stick a few gallons of water in the bed in case it starts to leak bad while on the road. 7.3 radiator swap is easy, I have not worked on a 6.7.
