Prepare your work area. Put a drop cloth on the floor to catch any paint splatters or spills. If you are not removing your windscreen before you paint, tape both sides thoroughly to protect it.
Sand the fairing with 80-grid sandpaper, using straight strokes in the same direction. You can use a belt sander, or do this step by hand. For curvy areas of the fairing, you'll need to sand by hand to get into all of the crevices. Sand the outside of the fairing to remove all of the old paint and to prepare the surface for the primer.
Repair any dents, scratches or holes in the bodywork. Your bodywork should be smooth before you begin painting. If the fairing has any damage, use a fiberglass repair kit to patch the holes, or to fill in scratches and dents. Once the repair work dries, sand it with the 80-grit sandpaper, ensuring that it is flush with the rest of the fairing.
Tape over the headlights with masking tape. The better the quality of tape, the better your headlights will be protected. Make sure you cover all of the surface area of the headlights and that the tape is secure. If you have difficult curves to cover, lacquer masking tape is flexible enough to conform to the curves.
Apply primer, using a spray gun or foam brush. A thick coat will fill in small scratches and give you a smooth surface. If you want your finished fairing to look its best, primer is a necessary step. Once it is applied, allow the primer to dry thoroughly.
Once the primer is completely dry, rough it up with 400-grit sandpaper. Run the sandpaper lightly over the surface by hand. This will make the paint adhere better to the primer.
Apply two coats of lacquer paint, using a spray gun, spray can or a horsehair brush. Each coat should be thin: the thickness should be just enough that the color is even throughout. Allow enough time between each application for the paint to dry.
Apply a top coat for protection and shine using a spray gun, spray can or horsehair brush. This layer should be applied in stages: apply three thin coats and allow each to dry before applying the next. Make sure you do this step after your second coat of paint has dried completely.
