What Is Rust-Oleum Paint

Rust-Oleum paint is a special coating to protect rusty or rust-prone materials and to prevent them from further damage. It comes in both spray or roller/ brush paint formats and is applicable on a wide variety of surfaces.

Depending on the chosen surface, it may take different lengths of time for it to harden. Ride with us through this brief article to learn more about it, and find out some tips on curing Rust-Oleum paint!

Do I Need to Paint My Bike with Rust-Oleum Paint?

Many bikers would be curious to find out the answer to this question. Generally, if your bike is in perfect working condition, it would not be a must.

However, there are some factors that make your bike prone to rusting. Firstly, where you store your bike matters. If it is usually kept outdoors, it would be exposed to weather elements and highly prone to rust.

Another factor is the conditions in which you regularly ride- if your bike frequently gets wet due to riding in muddy areas, or if it rains regularly in the areas where you go biking, you should also be concerned about rust. In such cases, applying Rust-Oleum paint is a logical step for prevention.

If rust starts to appear anywhere on your bike, Rust-Oleum paint is a convenient choice in order to stop the process and protect your bike from further rusting.

Before applying Rust-Oleum paint to your bike, there are some things to consider in order to make it work at its full capacity. In the hours after painting, the coating might feel dry to the touch. However, it may still be soft and prone to dents when in contact with pressing objects or straps.

Should you need more than one coating, or after applying the primer, bear in mind that drying times may vary. Since each product has different characteristics, you should always pay attention to the instructions on the paint can.

In order to help Rust-Oleum paint to harden, you can apply heat to the recently painted surface. All you need is a heat gun or even a hair-dryer. Just be careful not to apply much heat to any plastic parts you have painted, or that you were not able to disassemble.

The temperature at the spot where you paint the bike is also important. Hot and dry weather helps the paint adhere and cure faster and in a better way.

Another way to help your paint cure and harden is by applying a wind flow. This helps solvents to evaporate faster, making paint adhere, and helps prevent cracks and wrinkles from forming.

A larger consideration in whether to paint your bike might be that the aluminum frame, derailleurs, levers, handlebars, rims, hubs, rubber tires, and stainless spokes are not going to rust anyway. If you find yourself looking at a hi-ten steel frame, toss the whole bike and get a used aluminum framed bike from Craigslist. It’ll be night and day in usability.
The chromed bolts in the stem, bottle cages, headset, brakes, and derailleurs might rust, and switching them out for cap head M4, M5, or M6 stainless bolts might be a better choice than painting the whole bike.
An unplated chain might rust. Probably better to oil it than paint it.
