When repairing a car, you may be wondering how to paint over Bondo. Fortunately, it’s an easy task and requires little skill. If you want a nice finish, you can use Bondo body filler. This type of material is 100 percent waterproof and allows you to use a brush to apply the paint over it. The process takes only a few minutes, and the finished product is completely cured within thirty minutes.

Before you can start, you must make sure that the primer is completely dry. Usually, it will take 15 minutes to dry in a hot climate. In a cold climate, it will take 20-30 minutes. After that, you can use 3M(tm) sandpaper to shape the fill area. It’s important to note that you must prime the surface with primer before applying paint over it, as bondo absorbs moisture and can cause paint to bubble.

Before applying the primer, you must remove the bondo. The primer will absorb moisture and rust, so it’s important to protect it. In humid environments, it should be removed within three months. In desert-dry conditions, you should wait six months. Once the primer has dried, you can apply the topcoat to seal it. If the surface is rusty or has corroded, it’s best to paint over it.
