No sealant, I put in about 4 cups Prestone 50/50 left over from my daughter's car (1 cup in radiator/3 cups in dry overfill reservoir to max fill line). It is still bone dry and can't see where the leak came from after +2 weeks. The external RDX anti-freeze reservoir still shows full. Temp are going to get back into the 60s by Friday and I can double-check it then. Might have to remove the plastic cladding under the car to get a better look this weekend at the area at the bottom of the radiator.

Go to the auto parts and get a bottle of UV, get a uv flash light and you half way done to find the leak.

Update on my radiator leak. Turned out to be a hairline crack at the bottom of the radiator housing. Replaced and back to adding miles to the RDX.
