How to Refurbish Aged Motorcycle Plastic Shells?

For broken areas of the shell, they need to be bonded, filled with body filler, and then sanded. Other areas should be polished using 1000-grit sandpaper. After cleaning and drying, spray automotive paint, and if possible, bake it dry. Once the paint is done, you can proceed with personalized decorations such as stickers or color painting, followed by a coat of clear varnish.

Refurbishing motorcycle plastic shells starts with cleaning. As a long-time rider, I first use a soft cloth dipped in warm water with a bit of dish soap to carefully wipe the entire surface, especially areas with accumulated dust and stains, making sure water doesn’t seep in. Then, lightly sand the aged areas using fine-grit sandpaper or a specialized sanding block to gently remove the whitened oxidized layer—remember to wear gloves for grip. After sanding, clean thoroughly and apply plastic restorer evenly, letting it dry to restore deep color and shine. For cracks, it’s best to use plastic filler adhesive. Finally, apply a UV-protective clear coat to prevent faster aging from sunlight. Regular maintenance is crucial—I inspect mine every quarter, avoiding prolonged sun exposure and chemical corrosion. It’s cost-effective, extends lifespan, and makes the bike feel fresher to ride.
