The radiator was next on the task list. I took it out of the mounting bracket and found a surprise! Inside was a crusty, dirty radiator cap. Apparently someone dropped it between the radiator and the bracket and then couldn't retrieve it. It kind of makes you think about that person way back when and what frustration they had when that happened. There's a story there that's lost to time now.
I took the radiator to a radiator shop about an hour away. Seems like radiator shops are much fewer and farther between now. While I was there, I watched him re-solder a tank onto the core of someone else's radiator. It was actually pretty interesting. Of course, he made it look easy. Mine ended up needing a new core, so that was put in. I'm kind of surprised there is one available, but I guess you just have to match up the dimensions of the bare core, so it's probably pretty universal.
I media blasted the bracket and then treated it with Eastwood Rust Converter, then when that dried, I used the Rust Encapsulator. I then painted it with Chassis Black paint. It looks pretty good, not amazing, but pretty good.
I put it all back together and it looked much better.
