Rust Removal: The First Step to Painting
Rust removal is the first and most critical step in the process of painting over rust.

There are several methods for rust, including wire brushing, sanding, and using chemical rust removers. The choice of method depends on the extent of the rust damage and the type of metal.
Wire Brushing
Wire brushing is a simple and effective method for removing rust from metal surfaces. A wire brush is used to scrub the rusty area, removing any loose rust and debris. This method is best suited for small areas of rust and is often used in conjunction with other methods.
