Bullfrog® metal-seeking VpCIs seal and protect metals with a self-repairing “molecular umbrella.” The VpCIs migrate throughout liquid cooling systems, forming an invisible molecular umbrella of electrochemical inhibitors that seals all internal metal surfaces against the air and moisture that cause rust & corrosion both above and below the coolant level. There’s no effect on cooling system performance, and no chemical build-up – ever. Protection lasts until cooling system is flushed.
