Spoilers, sometimes called wings, are located on the rear of cars and are attached to the trunk lid. Spoilers are usually made of lightweight fiberglass or ABS plastic. Aftermarket spoilers come coated in primer or already painted, depending on the company and your choice. Most spoilers, even the painted ones, won't match your car so, you will need to paint yours. You can prepare and paint a spoiler in under an hour.
Things You'll Need
- 320-grit sandpaper
- Plastic prep
- Cotton towel
- Tack rag
- Adhesion promoter
Sand the surface of the spoiler with 320-grit sandpaper. Fold the sandpaper in half and use your hand to sand. Sand inside all crevices and corners, including any holes or designs the spoiler has. Sand until the spoiler is dull and has no glossy areas.
Wipe the surface with plastic prep and a cotton towel. Paint won't adhere to the smooth surface without plastic prep. Let the plastic prep evaporate.
Bend the end of a piece of wire and insert it into a bolt hole on the underside of the spoiler. Hang the spoiler from a rafter in the garage or someplace similar. Make sure you can reach all sides of the spoiler.
Use a tack rag to wipe the surface of the spoiler to remove all dirt and dust particles. Spray adhesion promoter on the surface of the spoiler and let it dry completely.
Spray the spoiler with paint, holding the paint can or spray gun 12 inches from the surface. Apply three to five even coats of paint. Wait five minutes between each coat.
Let the paint dry for a full day. Touch the underside of the spoiler to test the paint before you install it on the car.
Tips & Warnings
- It's best to remove the spoiler from the car before you paint it. If this is impossible, cover the trunk lid and rear of the car with paper and masking tape to protect them from overspray.
- Always wear a painter's respirator mask while spraying primer and paint.
- Never spray primer or paint inside an enclosed area without proper ventilation.
