How to Prevent Rust With Spray
- 1). Purchase a can of spray-on rust inhibitor at your local automotive supply store or hardware store. There are a variety of brands from which to choose. Most are fairly inexpensive and easy to use. Be sure to read the label on the can for specific directions and warnings.
- 2). Use sandpaper or a wire brush to remove any rust from an item that already has begun to corrode. If the item is painted with rust bubbling up from beneath, you must remove the paint and all signs of rust by sanding or brushing. You need to sand or brush down to the bare metal in order to protect it from future rust. Also, clean the object you want to protect, removing all dirt, dust, wax and any other debris.
- 3). Allow the object to air dry or dry it manually with a clean rag.
- 4). Spray the rust inhibitor onto the object you wish to protect from rust, coating the entire metal surface. If you're using a spray-on primer, the process is the same. You need to apply an even coat to the entire surface. If you're using both a rust inhibitor and primer, spray the rust inhibitor first and allow it to dry before applying the primer and any subsequent layers of paint. Follow the directions on the container for exact drying times and alternative application methods.
