Ofcr James,
I use a mix that I learned about here on Packardinfo. Half ATF and half Acetone. Amazing how this works. I used it on all the rusty stuff. Using a Mason jar with a lid, the acetone will evaporate over time, I just add more and use a paint brush. It will take many coats to get it loosened.
