The Free All Deep Penetrating Oil from FedPro is designed to spread deep into rusted or frozen parts, freeing them with ease. Free All is low-viscosity, high lubricity, and doesn’t evaporate, so it keeps eating rust until the job is done, the company says. It’s silicone-free, making it safe for use in paint and body shop environments. It comes in 11 oz. and is made in the U.S.
