Top 7 Best Rust Inhibitors

It’s almost unavoidable: rust will begin to grow on your vehicle, truck, or SUV over the course of months and years. If left untreated, it will grow and proliferate, eventually destroying the finish, structural integrity, and more.

Rust can occur almost anywhere: on your vehicle’s painted surface, deep beneath its floor, within its body panels, or even totally concealed from view behind plastic trim and weather-stripping. When rust begins to form, it is difficult to stop and extremely invasive.

Fortunately, there are lots of products available to assist slow or stop the formation of rust in and on your vehicle. Several accessories are also available to help protect your vehicle and prevent rust from forming in the first place. Read on for the lowdown on rust prevention for whichever vehicle you drive, and keep in mind that not all rust protection treatments are made equal.

#1 Rust Converter Ultra

Brand:  FDC

Rust Converter Ultra is a highly regarded, cost-effective, and simple-to-use solution to existing automobile rust issues. This surface conditioner, which is ideal for arresting existing rust or repairing and sealing frame rails, floor pans, and body panels on project vehicles, uses a chemical reaction to convert rust into a black polymeric coating.

Remove any existing rust scale from the area to be treated, leaving as clean and debris-free a surface as possible. The substance should then be applied with a brush or roller. When the coating has dried, it works as a primer and can be painted for further protection.

#2 CRC White Lithium Grease Spray

Brand:   CRC

CRC White Lithium Grease Spray is an excellent product to keep in your garage or toolbox to grease hinges, latches, and other similar components on your car, truck, or SUV.  An aerosol can contain high-purity lithium-based lubricants and oxidation inhibitors, and a needle tip enables precise application.

This type of rust inhibitor is commonly used on a regular basis to seal, lubricate and protect trunk and tailgate release latches, gears, tracks, power window slider components, throttle cables, rust-prone suspension mounting points, sunroof assemblies, and more. Lithium grease, which is typically used for spot application, is fairly expensive per unit, but the benefits are numerous: the product has a buttery, paste-like texture and is meant to stay in place without dripping or running.

The seal is watertight and corrosion-resistant, and the white tint makes it easy to see where it’s been applied. White Lithium Grease Spray is an excellent choice for strategic spot lubrication and rust prevention.

Wire-brushing the region is also advised. Allow Evapo-Rust to sit on the problem area for 24 to 48 hours before reapplying. Because it is reusable, the tool is also useful for soaking smaller items in a tub. Rinse
