The clear coat is water resistant and provides solid protection against environmental factors. The product is supplied as a liquid in a one-quart can, suitable for small to medium projects.

Praised for durability and ease of application, the fast hardener requires working quickly, which might be challenging for beginners. It is primarily intended for automotive or metal refinishing tasks, potentially being more than necessary for casual or decorative metal uses. For those seeking a clear coat with strong gloss, good durability, and suitability for professional or serious DIY metal projects, this Sherwin Williams clearcoat is a dependable choice, with the caveat of managing its fast drying time and mixing requirements.

Rust-Oleum's Painter's Touch 2X Ultra Cover Spray Paint in Semi-Gloss Clear is a convenient spray-on clear coat suited for metal and other surfaces both indoors and outdoors. Its oil-based formula offers strong chip resistance and durability, helping protect metal from everyday wear. The semi-gloss finish adds a soft shine that highlights the surface without being too glossy.

Application is straightforward thanks to an any-angle spray nozzle and comfort spray tip, making it easy to cover tricky spots. Drying time is relatively fast — it’s touch dry in about 20 minutes — so you can handle your project quickly. Coverage is decent at around 12 square feet per 12-ounce can, which is typical for spray paints in this category. As a spray paint, it requires good ventilation and some care to apply evenly without runs.

This product is a solid choice if you want a versatile, easy-to-use clear coat for metal that offers a durable, attractive finish, especially for general home or hobby projects. For those prioritizing maximum UV protection, clear coats with explicit UV-blocking claims may be preferable.

The KBS Coatings 8504 DiamondFinish Clear Coat is a versatile and robust option for protecting metal surfaces. As a moisture-cured urethane, it boasts impressive durability, flexibility, and resistance to corrosion, chemicals, and high temperatures. This clear coat can be applied over other coatings or directly to metal without significant surface preparation required, making it user-friendly.

One of its standout features is its high solids content (over 60%) and low VOCs, which contribute to its strong, hard finish that won't yellow, crack, or peel. Additionally, you won't need a hardener; just stir and apply with a brush, roller, or spray gun, and it will cure at room temperature (50° to 86° Fahrenheit). It's also suitable for automotive applications, including high-temperature areas like cylinder heads and engine blocks. However, it’s worth noting that the drying time is 24 hours, which might be longer than some users expect.

The product is also designed for professional-level use, which may present a learning curve for novices. Lastly, while it provides excellent chemical resistance (even against harsh substances like battery acid and brake fluid), ease of use in removing graffiti is a notable added benefit. In essence, this product is ideal for those needing a tough, long-lasting clear coat for both metallic and painted surfaces, particularly in automotive contexts.
