Whether you’re sealing a grill against rust or updating an old piece of metal furniture, spray paint provides a quick and easy way to get an even finish. Besides adding color to the metal, it offers excellent adhesion and higher durability. But that is only when you choose the right spray paint.
Even though most spray paint work on metal, not all can stand the test of time. Some may peel, crack or even swell up as soon as they are exposed to harsh conditions.
So, what is the most durable spray paint for metal?
That is exactly what we will reveal in this post. After much research and testing, we’ve finally compiled the top eight products that do not only adhere to metal but provide the best protection from rust and the elements.
Can You Use Spray Paint for Metal?
Yes, you can. Spray paint is highly durable on metal if you choose the right product. This could either be a specialty or general-purpose spray paint that works for metal. With any product, proper surface preparation is essential to achieve the best possible finish.
What Spray Paint Works Best on Metal?
When spray painting metal, the best choice is oil-based or hard-wearing enamel paint. Not only does it provide the best-in-class adhesion, but it’s also the most durable.
With proper prep, you can also use water-based acrylic spray paint, but oil-based enamel is generally better, especially for exterior surfaces.
Though oil paint takes longer to dry, it is highly durable and will resist stains and abrasion. It is also good at hiding flaws or imperfections in the material, though this depends on the type of finish.
In addition, oil-based paint performs better at lower temperatures. For metal surfaces that are constantly exposed to high heat, you might want to use a high-heat spray paint.
How Durable Is Spray Paint on Metal?
The durability of spray paint depends on a few factors, such as the brand, formula, thickness of the coating, weather conditions, and how well it was applied.
We’ve already established that oil-based enamel is the best spray paint for metal. But how long does it last?
Well, you can expect a service life of 5 to 10 years from a paint job done with oil-based enamel. On the other hand, with latex and water-based spray paint, you can expect 2-5 years and 1-3 years lifespan.
Things to Consider When Buying Spray Paint for Metal
1. Durability
Durability is extremely important, especially if you’re going to use the paint outdoors or in an area frequently exposed to high heat or traffic. Ideally, you want to ensure the paint is UV- and water-resistant. Otherwise, it would peel or fade sooner. Also, since you’re working on metal, you want something that offers rust protection.
There’s no sure way to know a product will be durable unless you use it. But you can still check the label. You want to look out for terms such as “outdoors,” “rust-protective,” “long-lasting,” “durable,” etc.
2. Drying Time
If you desire the most durable spray paint, you should care less about how long it takes to dry. However, if you’re in a hurry, then you might consider the drying time.
As earlier indicated, you can use either water-based acrylic or oil-based enamel spray paint on metal. Hard-wearing enamel paints offer the most durability but take a little longer to dry. Water-based acrylic, on the other hand, dries faster, but it is not as durable as enamel.
3. Primer or no primer
When spray painting metal, you would usually have to coat the surface with a primer before applying paint, especially stainless steel surfaces like Yeti cups. While this helps the paint to adhere better, it can be time-consuming. As a result, some manufacturers have primer mixed into the base paint to save time.
This means that if you decide to use such products, you won’t need to apply a separate coat of primer.
7 Most Durable Spray Paint for Metal Surfaces
1. Overall Best – Rust-Oleum 7579838 Enamel Spray Paint
The Rust-Oleum High-Performance Enamel Spray features a high-output tip that provides 50 percent faster coverage. The Any-Angle Spray is also capable of paint in all directions.

Once dry, the paint is weatherproof and doesn’t wash off or change color even in the rain.
Each aerosol can is 15 oz and covers up to 14 square feet.
It’s worth mentioning that the pressure on the nozzle can be a little too strong, which may leave big blobs of paint on your project. So, try to get some practice with it before using it in your main project. Also, shake well and test spray on some cardboard to prevent sputtering.

It comes in various colors and finishes, but our main interest is the black satin finish. This option is great because it provides a sleek finish to your project with some sheen. It’s also very durable and easy to clean.
But the best part is the maximum rust protection it provides. This means you can use the paint both indoors and outdoors.
As earlier indicated, the product includes a built-in primer, so you don’t need to apply a separate coat of primer. Sanding is optional, but we highly recommend it, especially if the surface is glossy. Sanding will help the paint stick better and ensure a smoother finish.

The paint dries to touch in 20 minutes. However, recoat should be done after 2 hours or 2 days. Use several light coats to avoid any drip or runs. Also, avoid spraying too close to the surface.

It is particularly targeted towards galvanized finishes, wrought iron, and spot-welded metal, as well as chain link fences and gutters.

The paint comes in a 20 oz bottle and covers up to 12 square feet.
For the best results, good prep work is required. Ensure there’s no dirt or grease on the surface. Besides cleaning with a soapy solution, you can remove oils with a degreaser. The surface must be clean and dry before you apply the paint.
Depending on the size of your project, you will need at least 2-3 coatings for good coverage and adequate rust protection.
The drying time is 30 minutes, which allows for quick project completion.
We recommend waiting a few days for the paint to completely cure before use. This is important to prevent leaving scratches on the object. We found that the paint hardens as it dries.
Luckily, you don’t need a top coat for this product. However, if you wish to apply one, it should be a water-based product or an oil-based product if you use a water-based primer.

Luckily, the paint has low VOCs (volatile organic compounds), so it’s not overpowering as most spray paint unless used indoors. So, ensure your workspace is well-ventilated. Ideally, you want to work outdoors.
You don’t need a primer to use the paint, which is a big plus as it reduces your prep work. However, ensure you remove all rust and dirt on the surface before you start painting.

Besides antique brass, the paint offers other color options and finishes. The metallic finish is perfect for metals; it looks like matte but has a sheen. So, it’s perfect for hiding imperfections while still making the metal pop. Choose gloss if you want something more shiny.

How To Spray Paint Metal Correctly
Now that you’ve chosen a spray paint, it’s time to start working. To use any spray paint, it’s best to follow the manufacturer’s instructions. This might slightly differ depending on the brand and metal you’re painting.
Here’s the general procedure:
Clean the object
Dirt and grease on the metal surface can prevent the paint from adhering well. So, the first thing you should do is to ensure the surface is clean and dry.
To clean the metal, you can use warm soapy water. Apply it with a clean rag and rinse with fresh water when done.
Large surfaces can be hosed down, or pressure washed.
Remove rust and old paint
Once the surface dries, get a wire brush and scrape off rust and old paint (if you’re applying a new color). Avoid using too much force on the brush so you don’t scrap off the metal along with the rust.
For better results, you can dip the brush into a cleaning agent like vinegar. Besides dissolving rust, vinegar also promotes paint adhesion.
After scrubbing, add 2 to 3 drops of liquid detergent in clean water, dip a clean rag into it, and use it to wipe off any rust residue on the metal object.
Allow it to air dry.
Apply primer
If the paint you’re using already includes a primer, you can skip this step. Otherwise, you will need to apply a separate coat of primer to prepare the metal for painting.
Primer acts as a base coat and helps the paint to adhere better.
Apply the primer according to the instructions on the label. One or two coats of primer are usually recommended.
Start painting
Once the primer dries, apply your preferred paint according to the manufacturer’s instructions. Remember to shake the can before use.
Hold it 6-12 inches away from the surface to prevent pooling. Spray in long sweeping motion using short spurts. Apply two or more light coats depending on the object you’re painting.
Allow the paint to cure fully before use. This can take anywhere from 24 hours to a few days.
Apply a sealant (optional)
Once the paint is completely dry, you can apply a clear coat or sealant for additional protection. Sealing prevents spray paint from chipping off metal. This step is completely optional and should only be considered if the object will be exposed to sunlight, heat, or moisture.
Tips for Spray Painting Metal Surfaces for Increased Durability
Before you start painting, make sure you’re well-protected. Wear a respirator or mask to protect your lungs, and cover your hands with gloves. If you’re using a rotary tool to grind away rust, using earplugs would be helpful.
Also, choose a well-ventilated space to work. Most spray paint releases toxic fumes, which can be harmful when inhaled for long periods.
Always clean the nozzle every time you use the paint, even if it’s for a few seconds. This will ensure it doesn’t get clogged when next you want to use it.
Surface preparation is everything when it comes to painting metals. So, don’t skip this step. Otherwise, the final result will not be good. Make sure the surface is clean and dry and doesn’t have any flaws.
The best way to apply spray paint is in a continuous sweeping motion. Spray back and forth, overlapping.
Make sure your hand is moving before you push down the trigger. Likewise, release the button before you stop sweeping over the project.
Spray from different angles to get a more complete and even coverage. Limiting yourself to one direction may leave patches on the final project.
Use light coats of paint to speed up drying and avoid drips on the project. It’s also a good idea to spray short spurts instead of a constant stream.
If you’re applying primer separately, make sure it’s compatible with the paint.
Don’t handle the object until it’s completely dry. If you touch it too early, you can leave fingerprints on the paint job, which can mess up the look when it finally dries.
Always do a test spray on a scrap material before painting the main item. This way, you can be sure the aerosol has no issues, and the color looks as expected.
FAQs – Best Spray Paints for Metal
Do you need a primer to spray paint metal?
A primer is generally needed when spray painting metal to ensure proper adhesion and even coverage. However, if the spray paint you’re using already includes primer, you can skip the priming step.

For maximum coverage and even finish, applying at least 2 light coats of paint is generally recommended. However, you can apply up to three or more for extra durability.

This depends on the particular product you’re using. In general, most spray paint dries to touch in 10-30 minutes and can be recoated after an hour or two. Full curing is usually reached after 24 hours or a few days. Other factors, such as the thickness of the coating and weather conditions, can also affect the drying time.
