In NB, what should I know about rust-proofing for car loans?
In New Brunswick, where harsh winters and road salt are prevalent, understanding rust-proofing for your car loan is crucial. While modern vehicles come with advanced corrosion protection and manufacturer warranties-typically 5-7 years for perforation-these often have limitations, excluding surface rust or requiring specific maintenance. When considering aftermarket rust-proofing, especially if you plan to keep the vehicle beyond the factory warranty, weigh the added cost, which can be financed and increase your total interest, against the long-term protection of your asset. Reputable oil-based treatments, applied annually, are generally effective and less likely to void existing warranties compared to some rubberized or electronic options which can sometimes trap moisture or have unproven efficacy. Protecting your vehicle from significant rust ensures better resale or trade-in value, mitigates costly future repairs, and helps maintain the integrity of your investment, which is particularly important given current (2025) market trends where consumers are keeping vehicles longer due to higher acquisition costs. Always confirm with your dealership how any aftermarket treatment might affect your manufacturer's warranty before proceeding.
