If your car has rust, you can be sure of one of two things: 1) the rust is not going away unless you do something about it, and 2) you have got rust in more places than the spots you can see. You basically, then, have two options on how to proceed.
Method one uses a body filler kit to repair the hole and protect it from the reoccurrence of rust. This method yields a strong, durable result, but it is time-consuming, messy, and involves many toxic materials. The item list for such a project will inevitably involve a body filler repair kit, breathing mask, drill with a wire brush, sandpaper, eye goggles, ball peen hammer, rust-resistant primer, paint.

Method two is less messy and less toxic, but it is also more time consuming and more expensive. You are going need a fiberglass repair kit and all of the tool and gear listed for the body filler job.
In today’s article, we are going to take a look at some of the best ways to deal with rust on your vehicle. Depending on your vehicle, your experience, and how much you want to spend on the repair, you will find that our guide will allow you to figure out what the best method to deal with rust on your vehicle is. Let’s get started!
The Best Rust Repair is No Rust, but there’s also Bondo
While any auto-repair specialist will tell you that the best rust repair is not to get rust in the first place, which means proactively washing and waxing your car, as well as touching up salt spots and scratches with manufacturer’s paint from time to time. The reality is, if you are reading this article, then you may just be a little bit past prevention.
However, you can’t always prevent rust, no matter how diligent you are. Not only that but because of the design of some vehicles, you are bound to get rust at one point or another, Not matter how diligent you are.
For example, Mazda Miatas, especially the older models, are notorious for developing rust in the bottom lip of the car. Additionally, SUVs and off-roading vehicles like Jeeps will often deal with rust on the undercarriage just because of the fact that these vehicles are more likely to experience exposure to moisture.
Because of this, it is imperative that you know at least a little bit about some of your product options. For this blog, we have chosen Bondo products, which are available on Amazon, and come with a combined 3.75 rating by 355 customers.

Best Rust Repair Wrap-Up
Popular Mechanics reminds us that it is best to correct surface rust as soon as you see it. This proactive step help to stop or retard the electrochemical breakdown of iron-based metals. This reaction happens when oxygen and the iron in metal (all metal has some amount of iron in it) meet, and the result is iron-oxide or rust. Auto manufacturers have invented crafty ways to try to “hide” the iron in metal.
But environmental variables like moisture and road salt can erode stainless treatments and metal polishes to expose the iron in metal. When this happens the iron is exposed to the air and rust begins to form despite metal treatments.
The best rust repair, is, of course, proper maintenance. But the fix for rust, once it happens, thanks to 3M and Bondo, is similar to touching up your paint job, and one must use an abrasive to sand off the infected rusty area until the clean, shiny metal is revealed. Next, wipe the area down with a cloth and apply your primer followed by a Bondo resin of your choice, sand, paint, apply a clear coat, and you are done.
