JohnDow Cre-Oil Professional-Grade Penetrating Fluid, part of the Dynamic chemical line, features a formulation with current chemistry modifications to make it into a penetrating fluid for auto service professionals. Cre-Oil comes in a 12 oz. can and has a low viscosity, allowing it to creep deeply and wick into tight crevices during repairs to chemically loosen rust and corrosion bonds created over time. Areas of application include pipe threads, pulleys, screws, fasteners, hinges, suspensions, chains, casters, cables, gears, electrical terminals, brake calipers, and more. Cre-Oil is formulated with aggressive solvents, wetting agents, and a specialty oil to break the surface tension of rust and corrosion. It does not evaporate, which helps with lubrication and stops further rust build up. Simply spray Cre-Oil on the impacted area and remove the nuts and bolts.
