I grew up using WD-40 as the cure-all for all life's woes. If it was stuck, rusted, squeaking, or needed some protection from the rain, then applying WD-40 was the go-to solution. As such, I've only bought JB 80 one time. I thought it was too oily and I didn't like the way it smelled. It claims to do the same things as WD-40. I think it worked a little better at removing bumper stickers and rust.
