How can I effectively spray paint a bike frame?

To effectively spray paint a bike frame, start by cleaning and sanding the surface to remove any dirt or rust. Use a primer to create a smooth base for the paint to adhere to. Apply thin, even coats of spray paint, allowing each coat to dry before applying the next. Finish with a clear coat to protect the paint. Make sure to work in a well-ventilated area and wear a mask to protect yourself from fumes.
