Show Coating of Soft Grease Prevents Rust Damage "Authorities viJ . agree that weath- f&tfrSQfr er often takes ,73"l& more out of farm A;".4uWnA machinery thangfljjfjl : j use, and rust has i j a way of creep- rfXj SSS'LA ing in even under y'T-.arvv good storage con- Fl ditions," says W. C. Krueger of Rutgers Rut-gers university. Tests have shown that crank case and transmission oil will prevent rusting from 7 to 30 days outdoors. Krueger reports. Axle grease and pressure gun grease gave protection from 60 to 90 days; five samples of rust preventive compounds for 276 days and nine samples for 305 days or more. On the basis of these tests, the best type of rust preventive is the soft grease type which may be brushed on metal surfaces to give protection for 10 months to a year. |
