The Verdict

PB B'laster penetrates deeper on seized bolts; WD-40 is the better all-rounder.

The age-old garage debate. WD-40 is a jack-of-all-trades — moisture displacer, light lubricant, and rust preventer. PB B'laster is a specialist: its sole purpose is penetrating corroded threads, and it does that job better. If you have one seized bolt, reach for PB. If you need one can that does everything, WD-40 wins.
