When should my car be rustproofed and how often?
Your car should be rust-proofed once every 12 months for optimal protection, though the best time of year to apply it depends on your specific goals. If your car has never been treated, the best time to do it is right now, as immediate application will instantly halt or slow down the oxidation process. [1, 2, 3, 4]
