GM Penatrant/Lubricant. Get it at a GM parts counter (yes, GM *DOES*
actually make something worthwhile!

Runs $8~12 depending how much of a discount the parts guy gives you...

Spray anything you want to work on a day in advance. Spray everything
else, too.

I had a Toyota Tercel that had the usual rust/corrosion, and sprayed them
with this stuff. Teo days later they looked NEW! Periodic sprays kept them
looking new, and made them easy to remove.
