Free All Deep Penetrating Oil, from Federal Process Corporation, uses unique silicone-free chemistry that easily and quickly penetrates the corrosion surrounding the rusted part or fastener to break it free without laborious and time-consuming torching, drilling or chiseling. Recent independent testing affirmed that Free All removed corroded bolts more efficiently that those treated with other leading penetrants. And unlike competing products, the silicone-free Free All formula is safe around paint and body shop environments.
