Just picked a used radiator and I want to clean it up right before I put it in my '64. Yes, I'd have rather bought a new one ... but couldn't afford it and this will be my sole daily driver in a few weeks.

Thing is, there's a bunch of red spray paint across the fins on one side (see pic). The other side looks good. Wondering if the paint will even effect the performance ...

Of course, I don't want to damage the fins. I've read that oven cleaner can work well, and that a caustic soda dip works too. Any idea on what that should cost? Funds are tight and I'm not going for a perfect restore here, just want it to function well.

Any tips on cleaning (inside and out), the paint issue, and on a good install would be appreciated.

The better side ... but still some bent fins
