You will win this battle, but it is going to take a while. You are correct, lots and lots of penatrating oil and time. I have found that 3-4 weeks of good soaking on something like this will yield results. Don't hammer too much, this can do more harm than good most of the time. Good luck and keep us posted.Thanks guys....I appreciate the help. I did try to do what the instructions you posted said...but to no avail. She's just been sitting too long. I will keep hitting it with the pb blaster and hope it works it's way in there.
