Yes, Tremclad is traditionally an oil-based rust paint, famous for penetrating and binding directly to rusty metal. However, they also offer water-based (acrylic) formulas.
Specially formulated TREMCLAD Water-Based Rust Paint is designed for use wherever traditional TREMCLAD Rust Paint can be used. It provides long lasting protection with excellent gloss and colour retention. Provides the ultimate protection in a water-based technology.
Tremclad and Rust-Oleum are effectively the same product line. Both brands are owned and manufactured by the parent company, Rust-Oleum. Tremclad is simply Rust-Oleum's primary rust-paint brand distributed predominantly in Canada, while "Rust-Oleum" is the globally recognized flagship brand.
A quick test you can do is to use DIGGERS Methylated Spirits and a clean rag. Put some of the methylated spirits on the rag and rub a small spot of the paint surface. If the paint comes off, it is water-based, but if the paint stays on and you get a shiny surface it is oil-based.
No other paint can equal Tremclad's long-lasting reputation for penetrating rusty surfaces and inhibiting rust. Because of this outstanding formula, Tremclad can be applied directly to surfaces you wish to paint and protect, providing long-lasting protection and durability.
Tremclad does not need a primer if you're applying it directly over mild steel, but that doesn't mean it's wise to forgo all surface preparation.
Oil-based paint is durable and glossy, making it ideal for high-traffic woodwork but it's being phased out due to environmental concerns. The strong odors, long drying time, and yellowing over time are key drawbacks of oil-based paints.
Oil-based paint is most commonly referred to as alkyd paint or solvent-based paint.
Sinclair agrees: “Items such as interior drywall have no need to be painted with enamel,” she asserts. “You will likely not want a hard glossy finish on your walls.”
It has been the most common technique for artistic painting on canvas, wood panel, or copper for several centuries. The advantages of oil for painting images include "greater flexibility, richer and denser color, the use of layers, and a wider range from light to dark".
TREMCLAD® Professional Rust Enamel offers superior coverage and rust protection. It's a coating tough enough for industrial applications. High output tip results in faster coverage to get the job done quickly.

Better to apply three light coats rather than two heavy ones. In fact, if you apply too much Tremclad in one place, the surface of the wet area will dry faster than the underlying liquid paint, causing wrinkling.
Good Paint
I find Tremclad always lasts welll but you must use 2 coatd if you are painting over rust. It is better than Rust-Oleum.
Painting water-based paint directly over oil-based paint usually leads to poor adhesion, chipping, and peeling. Because oil and water don't mix, the water-based paint cannot properly grip the smooth, slick oil surface. Over time—or even with light scratching—the paint can flake off in large chunks.
Red is universally considered the hardest paint color to cover. Vibrant red pigments are highly transparent and inherently prone to bleeding through subsequent layers. Other notoriously difficult colors to cover include black, dark blue, dark green, and bright yellow.
A primer is not essential on clean, bare ferrous surfaces that are sound and free from grease or oil. Paragon Enamel will adhere directly to properly prepared bare metal and can be considered self-priming in these situations.
The healthiest paints for interior walls are natural mineral-based (clay or lime) or plant-based formulas. These eliminate synthetic plastics, toxic off-gassing, and Volatile Organic Compounds (VOCs).
Enamels may also contain antimony, arsenic, barium and cadmium. These are all harmful if ingested or inhaled.
To clean brushes, rollers, and other painting tools after using oil-based paint, you need mineral spirits or turpentine—harsh chemicals that can be difficult to handle and dispose of properly. These solvents not only add to the cost and complexity of the project, but they also present health and environmental risks.
The best oil paint alternatives include water-mixable oils (for the exact same feel without toxic solvents), heavy-body acrylics (for fast, odorless, and water-based work), and gouache (for quick, matte opacity). Choose based on which oil characteristics you want to keep or replace.

Professional artists use both acrylic paint and oil paint depending on their style and the demands of their projects. Many artists who work in realism or portraiture prefer oil paints for their blending capabilities and depth of color.
You can often use old paint if you mix it very well, but several factors determine its usability. The general paint shelf life for unopened latex paint is around 10 years, and oil-based paint can last up to 15 years. Once opened, this lifespan typically reduces to a couple of years, depending on storage conditions.
Oil-based paint is generally not toxic once it is completely cured. While high levels of Volatile Organic Compounds (VOCs) and petroleum fumes are emitted during the drying process, these chemicals steadily drop to safe, negligible levels once the paint is fully hardened.
