Metal Guard 310 is an economical and versatile rust preventative, which leaves a corrosion-resistant, semi-dry film. Metal Guard 310 can be mixed with water in proportions ranging from 5 to 50% by volume, depending upon the desired degree of dryness and final film thickness. A “dry-to-the-touch” film is obtained on zinc phosphate surfaces when mixed at a ratio of one-part Metal Guard 310 to 8 parts of water. It is heated to 150°F, and is applied by dipping, spraying or brushing.
