Rust Protection Using Clear Coat While Keeping a Rust Patina Look
Patina is a thin layer that develops on the surface of metal, wood, leather, and other materials which gives an aged look. Patina can be the result of age, exposure to the sun and moisture, as well as wear. A patinaed look can also be brought about artificially with things like chemicals, specialty coatings, and abrasion. Rust can be considered a desirable patina, however, left unchecked it can eventually eat metal away completely. Every now and again we get inquiries from customers who would like to keep the patina look of rusted metal, heighten rust patina appearance, while also protecting the metal from further rusting. When asked for advice on coatings that can be used to get these results, we recommend DiamondFinish Clear and KBS MAXX Clear for rust protection using clear coat to keep and maintain a rust patina look.
Rust Protection Using Clear Coat
To stop rust, rust must be separated from oxygen and moisture. DiamondFinish Clear and KBS MAXX Clear coats can be used to seal rust and provide rust protection with a durable impervious barrier that blocks moisture and oxygen from reaching metal surfaces. By using a clear coat for rust protection, the rust patina look will remain, but the rust won’t continue to progress.
Preserving Rust Patina with Clear Coat
Rust patina can be a delicate thing. Since rust can be powdery, or flaky, it is susceptible to being marred by impacts and abrasion. A clear coat provides a hard, durable, protective coating that can preserve rust patina. Another benefit of sealing rust with a clear coat is the rust won’t be exposed, so it won’t rub off onto clothing and other items.
Enhancing Rust Patina with Clear Coat
A clear coat brings out richness in rust colors and gives depth and luster. Applying a clear coat to seal rust patina gives it a beautiful wet look and adds a darker tone and contrast to the color of the rust.

- Before applying a clear coat to rust, remove loose rust flakes with a wire brush. You do not have to be aggressive, but you want to remove rust that is falling off the surface.
- Clean the surface with KBS Klean mixed with warm water in a 1-1 ratio. A cloth can be used to scrub the surface.
- Rinse with water and allow the surface to dry thoroughly. Many times it is best to force dry to get all of the water out of the rusty surface which tends to be porous.
- Apply a minimum of three coats of DiamondFinish Clear or KBS MAXX Clear. The actual number of coats can vary based upon the coarseness of the rust. It’s important that the peaks and valleys of the surface profile are completely sealed to prevent rust and corrosion from spreading down the road.
SPECIAL TIP: DiamondFinish Clear and KBS MAXX Clear can also be used to seal non-rusted, bare metal to keep it from rusting.
