Rust on your car is annoying, no doubt! You’d love to make it disappear quickly and easily. So the thought is tempting: Just spray some paint directly onto the rust and you’re done, right?
But is this method really recommended? Can you apply spray paint directly to rust? In this article, we’ll get to the bottom of this question and show you how to effectively combat rust.
What Happens If You Spray Paint Directly on Rust?

Imagine rust as an invisible enemy that keeps spreading. Rust is an oxidation process that attacks the metal and slowly destroys it. If you simply apply paint over it without removing the rust beforehand, you’re providing it with a perfect environment to continue growing. The rust can continue to work unnoticed under the paint layer and further increase the damage.
Professor Dr. Markus Schmidt from the Technical University of Munich explains: “The paint cannot permanently keep out moisture, and the rust continues to spread beneath the surface. The result? The paint flakes off and the rust reappears.”
So, How Do You Properly Deal with Rust?
To effectively combat rust, it must be thoroughly removed. Here are the most important steps:
1. Rust Removal:
- Mechanical Removal: Using sandpaper, a wire brush, or a special grinding tool, you can manually remove the rust. Make sure to remove even the deeper layers of rust.
- Chemical Removal: Rust converters transform rust into a stable compound that can be painted over. Be sure to follow the manufacturer’s instructions for application.
2. Primer:
After rust removal, a primer is essential. The primer protects the metal from new corrosion and ensures better adhesion of the paint.
3. Painting:
