Abstract
Adding a combination of sterically hindered tertiary amines or derivatives, e.g. piperidine and derivatives, with overbased metal (e.g. calcium, magnesium, barium, zinc, etc.) sulfonate, wax and oxidized petrolatum solvent based rust preventative compositions dramatically increases weather and salt-fog protection.
