Leaking hot water radiators

Hello!
I am new to the forum and hoping to find some help. I recently had two old cast iron radiators from my 1900s Philadelphia row home (which had been in perfect working order) sand blasted and powder coated by a local place. After hooking them back up and starting to pressurize the system, I discovered that there were small leaks between multiple sections of the radiators. I tightened down the bolts on the sides, which seemed to work a bit for one of the radiators but not for the other.
Does anyone have any other suggestions? Do I have to scrap my beautiful new radiators?
Thanks!
Rebecca

Try tightening again with one person on each end going together.0

That's the down side of powder coating old rads. Baking process can destroy the paper gaskets.

I have used Fernox cleaner and protector and like their products. Didn't know they made a sealer. Would definitely give it a try0

Those radiators have push-nipples in them, which can be replaced, and any gaps sealed with hi-temp silicone caulk. Do Not over-tighten the rods or you may crack the radiators.All Steamed Up, Inc.
