Why We Need To Use Coat On Metal Items?
1. Texture Protection
Using clear coating on metal surfaces provides a wholesome defense against various quality degraders, without disrupting the original texture.
It can save your bare or painted metal accessories from atmospheric enemies like rust and corrosion, created by unguarded exposure to humidity, heat, and rain.
Coating painted metal accessories can save the painted surface from structural damages like chipping, creasing, and fading.
2. A Glossy Finish
Coating metal surfaces and accessories can offer a permanent and shiny finish to their color.
Coating products often use elements like Acrylic Lacquer that not only preserves the painted surface but also increases its shine and glaze. Since coating prevents discoloration and yellowing, the paint on your metal objects will not only achieve a new glamour but also be able to keep that glaze consistently.
3. Increased Durability
Researching a number of studies, we have found that a clear coated metal object has a noticeably longer term of durability than an uncoated one.
Even setting aside the statistical proofs, common sense also dictates us towards the same conclusion.
Coatings protect both bare and painted metal surfaces from multiple atmospheric and structural degraders (e.g. corrosion, cracking, etc.). Thus, coated metal objects tend to last longer and shine brighter.
4. Restoration Of Old Metal Accessories
Clear coatings can also be used to restore the glory of old metal items, such as jewelry, automobile parts, furniture, etc.
5. Outdoor Friendly
If you prefer to do metal crafting or professional builds outdoors, then using clear coating products is a must.
If your painted metal surface suffers long term exposure to sunlight, the UV rays contained in it will ruin the texture. So, by using a clear coat you can stop phenomenon like these from happening, as it blocks UV rays to protect your painted surface from damages like yellowing, cracking, creasing, fading, and discoloration.
6. An Intelligent Investment
Purchasing a clear coat will pay for itself.
If you spend a large amount of money on buying and painting metal accessories, then a simple addition of a clear coating will protect that investment for a long time.
Otherwise, you might spend all the bucks and do all the work, only to let it get ruined by minor issues like a highly humid atmosphere or an unfortunate scratch mark.

10. Rust-Oleum, Painters Touch Quart Latex Clear Gloss 242057
Rust-Oleum has a reputation of creating coating products that ticks all the right boxes. We are glad to report that the Painter’s Touch 24205 walks in the same path.
The product contains 887-milliliters of liquid in a perfectly symmetrical, (5x5x5)-inch can. It is sealed by a multi-circular ridged, push-in cap. However, if you face difficulty opening the container, jam a flathead screwdriver between the circles and press upwards.
The coating follows a single-step application, meaning you can use it right out of the container without any prior mixing. Though, the manufacturer advises to sand, degrease, and dry the surface before applying coating.
The product offers a half an hour dry-to-touch time and the coated surface can be used after only an hour of application. For a full-cure, we recommend waiting at least 4 hours. After this period, you can even recoat the surface.
However, the time measurements will be accurate if the coating is done at an atmosphere with a 25-degree Celsius temperature and a 50-percent relative humidity. If you are working in colder conditions, the drying and cure time may increase.
The coating doesn’t require additional thinning. It is eligible to protect metal surfaces from both atmospheric (moisture, heat, etc.) and structural (chipping, discoloration, etc.) damages.
The manufacturers use an aqua based acrylic method, which makes it odorless, low in VOC count, quickly dryable, and substantially durable. It also provides a shiny finish, UV-resistant properties to prevent yellowing, and similar compatibility for both indoor and outdoor use.
The product can cover up to 120-square feet of metal surface and offers a super clean coating that doesn’t interfere with the original texture.
11. TotalBoat, Epoxy Resin & Hardener Kit TB-9334
This product is another great epoxy resin in this list that is designed to finish up large-scale coating projects.

How to Choose Right Clear Coat For Metal?
1. Quality And Options Of Offered Protection
The primary reason to coat a metal surface is to provide protection to its bare or painted texture. Thus, choosing the right clear coat largely depends on the quality and options it offers in terms of texture preservation.
We recommend purchasing a clear coat that offers atmospheric protection as well structural integrity.
Atmospheric degraders like humidity, moisture, heat, dust, and UV rays from sunlight (which causes yellowing of a painted surface) can significantly damage a metal surface.
These degraders cause both bare and painted metal to become rusty, faded, yellowed, and discolored. Thus, ensure that the clear coat you’re purchasing provides protection against these factors.
Another issue is structural integrity. By this term we mean, using a clear coat that doesn’t let the metal surface crack, crease, and peel off, while eliminating any scratches and score marks.
2.Design Of The Container
Though it may seem like a minor feature, choosing a functional clear coat is intricately connected with this factor.
If you purchase a coat that comes in a poorly sealed container, equipped with a lousy nozzle, and doesn’t fit into a standard sized shelf, it’s likely that you won’t have much fun using it.
So, choose a product that uses a metal or premium grade plastic body.
Make sure that the cap is easy to use and provides a proper sealing. Otherwise, your coating liquid will fall prey to oxidation and auto evaporation, slowly losing its quality and amount over time.
Now let’s talk about the importance of nozzles, in case you choose to use a spray coating. We recommend getting a nozzle with a modern design.
For example, the “EZ Drip 360” nozzle. It reduces finger-stress despite long hours of use and provides a free-angle spraying range to reach tricky parts of the surface. It also lets you to spray as close as 3-inches from the surface, providing you more control and precision over the coating process.
3. Drying And Cure Time
If you prefer to do your metal coating outdoors and care about your workflow, then pay attention to these features while purchasing a clear coat.
We recommend buying a product that provides a fast drying (minimum 10 to 30-minutes) and full-cure (at least 24 to 48-hours) time.
If you are coating outdoors, a slower drying time can make the coated surface a victim to prolonged exposure to UV rays coming from the sunlight. This can ruin the coating by causing issues like yellowing, cracking, or creasing the texture.
Similarly, a slower cure time will reduce your ability to complete projects quickly, even if you are working indoors.
4. Health Safety
You should always purchase clear coats that are approved by the FDA and comes in a BPA-free container.
Also, ensure that the product has a low VOC count, which means it contains very small amounts of organic compounds that can be a threat to your health. You should also look for non-toxic clear coats, otherwise the coating may start to emit harmful chemicals after a couple of days.
5. Application Method
Clear coats for metal accessories are usually equipped with the following application method:
- Single-step: This type of coating doesn’t require any mixing. They come pre-mixed with prepping elements like hardeners and primers.
- Double-step: This category of coatings contains two separate containers, one for the coating liquid (e.g. epoxy resin) and another for the hardener. They need to be mixed at a certain ratio before application. The common practice is using a 1:1 ratio.
Another way of describing the different application methods would be brush-coating and spray-coating.
- Brush-Coating: It is done using paint brushes. It allows you more control over the coating process and is an ideal choice for those who want to experiment with different layer techniques.
- Spray-Coating:It is a faster process. It also requires less effort on your part, as they usually come pre-mixed with primers and hardeners. The amount of manual labor is also significantly less in this method.
To summarize: this factor depends entirely on your preference, as each method has its merits and demerits. So, we recommend choosing a method that suits you.
How To Apply Clear Coat On Metal?
1. Clean The Surface
The first step is cleaning the surface.
For bare surfaces, if there is light and unattached rust, you can simply brush them off or use a compatible scrub. For old rusts, use a rust converter for removal.
In terms of painted surfaces, the cleaning process is largely similar.
However, if the paint is too flaky and old, you may need to use professional tools to properly remove them and repaint before applying the coating.
If the paint is new, then allow it to set in properly before beginning to dust off and clean the surface.
To clean grease off bare surfaces, use petroleum spirits and a soft fabric. Be gentle with cleaning painted surfaces, as an uneven texture won’t allow the coating to set in properly.
2. Prime The Surface
Most clear coats come pre-equipped with a primer. Therefore, you can directly go to the coating procedure.
Also, certain metals like Stainless Steel is less prone to oxidation compared to other metals like aluminum. So, you usually won’t need to prime a stainless-steel surface, but an aluminum surface may require some priming.
We recommend using clear coats like Krylon'sColorMaster that uses a coating pre-mixed with a primer. This way, you can skip the trouble of manually priming a surface and go straight to coating.
3.To Brush Or Spray?
At this point you need to choose between brush-coating and spray-coating.
Brush-coating offers more control in terms of putting down layers but requires more manual effort. They also usually follow a double step application method where you need to mix the coating and hardener yourself following the proper ratio. For professionals, who are looking to finish a large coating job and have years of experience, this maybe the better option.
In terms of spray-coating, generally they’d come pre-mixed (coating + hardener) and requires less physical effort to use. They can also be applied faster than brush-coating and are able to reach difficult spots and corners of the surface. However, they may provide less layer control and usually shipped in smaller amounts.
4. Layer Properly
A wrong technique of layering can ruin your project, even if you are using the best clear coat for metal surfaces. Thus, getting it right is indispensable.
You need to lay a few thin layers of coating first (also known as primary coating) and allow it to set in. Then, apply a second layer of thicker coatings. Once the second layer sets in properly, apply the final layer of coating known as a top-coating.
5. Allow Proper Dry, Cure, And Handling time
The final step is all about patience. Let the coating to dry and cure completely per the manufacturer's instruction.
Also, note that a full cure time can be different from handling time (a particular time period from when the coated surface can be used). If so, do not use the cured metal prematurely.
FAQs on Clear Coat For Metals
1. What Is A Hardener?
Answer: A hardener is an essential component of a clear coating product. It helps the coating to set in properly and maintain a strong structural integrity.
2. What Is The Difference Between Primary, Base, And Top-Coating?
Answer: Essentially, they are simply the name of different levels of coating that occurs through the coating process.
Primary coating is the first few, slim layers of coating that begins the process.
Then, after a certain period (depending on the product), the middle layer is applied, which is known as the base coating.
The process ends with a final layer of coating, usually recognized as a top-coating.
3. Should I Take Any Precaution Before Beginning The Coating Process?
Answer: Clear coats are generally non-toxic, FDA approved materials that have a very low VOC count.
However, you can still wear protective glasses, a leather/plastic apron, and an APR (Air Purifying Respirators) for extra vigilance.
4. What Type Of Clear Coating Is Better For Automobiles Parts?
Answer: Since automobile parts are more sensitive to outdoor atmosphere and require a faster workflow, we’d recommend using spray-coating for this purpose.
It also causes less finger fatigue and provides a flexible coverage by using “free angle technology” equipped nozzles to reach tricky spots.
Another factor would be the less application distance (e.g. 3 to 4-inches between you and the surface), which can help you to do a more detailed coating job without sacrificing speed.
5. Can I Use Clear Coating On Metal Jewelries?
You can use clear coats for metal jewelries as well. In fact, clear coat is often used to restore old metal jewelries and to preserve their color and glaze.
However, the process will be subtler and detailed than coating larger surfaces. So, if you are a beginner, consider taking the help of a professional in this case.
The role of clear coatings in increasing the glory, protection, and longevity of your metal objects is like an optical illusion. You usually won’t see it. But once you do, it can’t be unseen.
Though, even after understanding its importance, you may face a hard time picking out the best clear coat for metal accessories used on a daily basis or cherished as a prized possession.
However, since you’ve reached at this point, we think that’s quite unlikely to happen.
If you can use this guide to find the perfect coating for protecting your metal possessions, our efforts in creating it will be more than worth it.
