Military-Grade Rust PreventionModeled after Military Specifications: MIL-PRF-16173, Grade 4 and MIL-C-83933.Application:IMPORTANT #1: Make sure your surface is clean and dry (not oily or greasy) to ensure best possible adhesion.IMPORTANT #2: RP-342 is a heavily-concentrated rust preventive. For best results, each spray can should be shaken vigorously for about 2 minutes to ensure a uniform coat. The aerosol cans should also be shaken intermittently during longer application sessions.GENERAL INSTRUCTIONS - Spray a generous, even coating on your surface and let dry. While a single coating will provide exceptional protection, additional coats can be applied if desired. If applying multiple coats, always let previous coats dry completely before applying the next coat. Ideally, it’s always preferable and recommended to apply over a non-rusted surface, however, RP-342 can be applied over moderate surface rust. RP-342 will prevent surface rust from spreading.
