I think it took something like 6 months for my tendons, ligaments, and muscle fibers to reconstitute themselves after I went through that gymnastic routine a few years ago. I think AutoZone lends the special wrenches out for free, after you put down a refundable deposit; nice to see though that you found one for cheap money. You're right, a good soaking with WD-40 is in order, and a breaker bar is a big help. It probably helps too if you can put the car up on a lift, as opposed to jackstands, the way I did it, but that luxury isn't always available.
