My favorite wrench is "liquid wrench" used with a "monkey wrench." Nothing beats a good old pair of vise grips and an tetnus shot once in a while! I have a hard time finding a 4 sided deep socket to remove the 2 inch long rusty fender bolts that some jerk put on 40 years ago because he couldn't find the right 1/2 inch long bolt to use. It doesn't seem to matter what kind of tool you have when most of the rusty bolts simply twist off....ah the "liquid wrench!"
