Guy's need a little help. I have a 37 Cadillac, and the butterfly hinges on the hood are rusted to the point the hood will not open. Anyone have any ideas how to unfreeze these hinges. If you're not familiar with these they look like long piano hinges.

I've tried soaking in WD-40, any other ideas?

Can you get at the pin with a thin cutoff wheel at each gap and get a new pin later? Check this similar hinge fix/work

Yea Milo, I thought about that. The problem is, there really isn't much of a gap between the hinge to cut the rod. If I do that I will end up making a larger gap. If I have to I can do it.

Just wondering if there is any other suggestions before I bring out the cutting tools.

When it comes to penetrating oil, I think KROIL by Kano beats anything else, especially WD-40. I'd try burning the WD-40 out with a propane torch, letting it cool, then squirting Kroil along the hinge. Let it sit overnight, then try working the hinge a little at a time maybe applying a little heat again.
It also helps to add some impact vibrations to help the Kroil soak in and loosen the rust. Try tapping on each hinge node between a hammer and a bucking bar while its soaking.
Of course your hinges ARE 67 years old now, so.....
