Best Penetrating Oil?

[psdenno]

To bring closure to the "rusted nuts" on the bumper saga, here's what happened.  I took the rear bumper to a machine shop.  Who better to resolve the issue than professionals who work with corroded metal every day?

They kept it for several days, soaked it in a combination of acetone and ATF, added a little heat, and eventually got the rusted nuts off of the 50 year old bumper and over rider without breaking either of the threaded mounting studs.

All good,  I just need to clean it up and install the new rubber strips on the over riders and the bumper ends.  A weekend project if the temperature stays below the 122º level it hit earlier in the week.

Thanks to all who offered suggestions!

Good to hear! Also good to know professionals use acetone and transmission fluid.
