Claim Text:
1. A storage stable composition made by mixing together a first mass of water and at least the following components: (A) a second mass of a water-soluble source of fluorometallate anions to provide in the composition from about 1 to about 100 g/kg of the fluorometallate anion, each of said anions consisting of: (B) a third mass in an amount of about 23 g/l to about 100 g/l of a water soluble source of chromium fluoride; (C) an optional fourth mass of water-soluble source of fluorine anions; (D) an optional fifth mass of a component of surfactant and/or water soluble thickener; said composition being free of water-soluble organic corrosion inhibitor and water-soluble organic stabilizing agents, having a pH of at least 2.1 and no more than 4.4, being storage stable at ambient temperature for at least 2 weeks and capable of producing no more than 3 pits per panel after being exposed to 336 hour salt spray testing according to ASTM B-117.
