Fix Droopy Fairing On Mirrors

A mirror attaches to a motorcycle frame by means of a fairing.

The fairing on a motorcycle mirror is the piece of plastic that attaches to the motorcycle frame and holds up the mirror. If the fairing cracks or breaks, the mirror will droop and sag. Eventually, the weight of the mirror on the crack will break it off completely. You should repair a damaged fairing right away to prevent a more difficult or expensive repair down the road. Fiberglass is an effective patching material that will add strength to a drooping mirror fairing.

Instructions

1. Sand the fairing around the cracked area to smooth it down and remove rough edges from the surface. Wipe away the sanding dust with a damp cloth.

2. Cut a strip of fiberglass sheeting one inch larger than the crack on all sides. Cut two strips, one for the top of the crack and one for the underside. You may have to unscrew the fairing from the motorcycle frame to access the other side of the crack.

3. Apply resin to the top and bottom of the crack using a small paintbrush. Press the fiberglass sheets over the crack. Apply a second layer of resin over the top of the fiberglass sheets. Hold the fairing in the correct position with clamps for support as the resin dries. Let the resin dry for 12 hours. Apply a second coat of resin over the first coat. Let this second coat dry for 24 hours.

4. Sand the surface of the resin down with a sanding wheel to blend in the repaired area. Wipe with a damp cloth to remove sanding dust.

5. Fill in the area around the patch with auto body filler to conceal the repair. Allow the filler to dry for 12 hours, then sand it smooth with the sanding wheel. Add more filler as necessary to create a smooth surface on the fairing. Reattach the fairing to the motorcycle frame.
