Confusing Radiator Leak

1994 F-250 just turned 140,000 miles. I take better care of this truck than the little woman. She began with a little weeping from the passenger side fender panel. I let it go for a week to see what more would happen...waiting to see if the heater core was going bad. This morning, I found a little green puddle on the backside of the radiator around the top seal and "cap." I have used Bars Stop Leak on other occasions in the past and have had very good luck. Although hesitant about putting the Stop Leak in this vehicle I need to put a stop to this leak and am asking this question????
WHAT is the best product (Stop Leak) for my application? Stock 1994 Ford F-250 I'm sure it has the stock Ford radiator. For starter's, I am not too thrilled about the copper pellett product...I appreciate your comment's!

Found out that this is real common on Ford diesel radiators. I went to my radiator shop and since I have a 2015 and they will not release to plastic end covers until 2020, I would have to replace the radiator. He gave me a tip and sent me down to the local AC Delco parts dealer to get AC Delco Cooling System Seal Tabs. Disconnect the upper hose, put three tabs into the radiator and reconnect the hose. PROBLEM FIXED for $2.41.
