Removing Rust From Your Classic Car: Sandblasting, Chemical Rust Removers, and More

Removing rust from your classic car can be an enjoyable part of the restoration process! There are several methods you can use to banish that rust and get your vehicle back to its former glory.


If you have heavy rust over large areas, sandblasting is the way to go. This abrasive method uses compressed air to blast tiny particles of sand, glass, or other media at high speed to remove rust and paint from metal surfaces. It’s fast, effective, and leaves you with a smooth blank canvas for new paint. Exciting.

Chemical Rust Removers

For smaller rust spots, you can try chemical rust removers. These commercial products contain acids and inhibitors that chemically convert rust into a water-soluble compound that can be scrubbed off. Just brush the product on, wait, then scrub with a wire brush. Many restorers have found success with these convenient solutions.

Elbow Grease

Sometimes good old-fashioned elbow grease is all you need! Wire brushes, steel wool, and sandpaper can work wonders on surface rust. Scrub the rust off then sand the area to rough up the surface, so the new paint will adhere properly. A little sweat and muscle can save you money and give satisfying results.

With so many options, you’re sure to find a rust removal method suited to your needs and skills. Bust out the tools, crank up your favorite tunes, and get scrubbing – your classic car will be rust-free in no time.

Preventing Rust on a Restored Classic: Primers, Paints, Undercoatings

Once you’ve removed the rust from your classic car, it’s time to take steps to prevent its return. The key is protecting the bare metal surfaces of your vehicle. Here are some of the best ways to shield your ride from future rust:

Primers and Paint

The most effective rust prevention is a quality primer followed by a durable topcoat of paint. Primers are designed specifically to adhere to bare metal and provide a base for paint. For maximum protection, apply 2-3 coats of primer and 2-3 coats of paint. Spray-on products tend to provide the most even, durable finish.

Rust-Preventative Undercoating

For areas like the undercarriage that are difficult to paint, rust-preventative undercoating is ideal. These thick, wax- or asphalt-based coatings seal out moisture and last for years. Popular brands like 3M and Fluid Film offer heavy-duty undercoatings perfect for classic cars.

Electronic Rust Protection

If you want to protect the nooks and crannies without heavy coats of primer or undercoating, consider an electronic rust protection system. These systems use a low-voltage current to set up an electrochemical reaction that inhibits rust formation. Brands like CorrosionX and Woolwax are trusted by many restorers.

Keeping your classic car rust-free requires vigilance, but with the right combination of primers, paints, undercoatings, and rust inhibitors, you can display your vehicle with pride for decades to come. Stay on top of any scratches or dings and continue to inspect, wash, and re-treat as needed. Your car is worth the effort.

DIY rust removal methods

Be sure to wipe away dust with tack cloths as you go to check your progress.

Apply the product as directed, wait, then scrub with steel wool and rinse thoroughly with water. These chemicals can be harsh, so wear proper safety gear like goggles, gloves, and ventilation masks.

Abrasive blasting is a fun method using pressurized grit to blast rust away. You can rent affordable abrasive blasters and abrasives like aluminum oxide or garnet. Blast in short strokes, keeping the blaster nozzle at a 45-degree angle and 6 to 8 inches from the surface. Wipe away debris and repeat until all rust is gone. This method requires safety gear and contains the mess.
