Painting Fairings With Spray Paint – Achieve A Factory-Quality Finish

ByJim Boslice Metalworking & Fabrication

To achieve a professional result, start by thoroughly cleaning the plastic with a wax and grease remover. Sand the surface with 400-grit paper, apply a plastic-specific primer, and use high-quality 2K clear coat for a fuel-resistant, high-gloss finish.

The secret lies in the preparation and the environment; always work in a dust-free area and apply several thin “tack” coats before your final wet pass to prevent runs and orange peel.

Most riders believe that getting a showroom finish on a motorcycle requires a professional paint booth and an expensive HVLP spray gun setup. You might feel hesitant to touch your bike’s plastics, fearing that a “rattle can” job will look cheap or peel off after the first ride.

I promise you that painting fairings with spray paint can produce stunning, durable results if you follow a disciplined process. By using the right materials and taking your time with the preparation, you can save hundreds of dollars while customizing your ride exactly how you want it.

In this guide, we will walk through the entire workflow from stripping the old finish to the final buffing stage. We will cover the specific types of paint that bond to ABS plastic and how to ensure your new look stands up to UV rays and gasoline spills.

Why painting fairings with spray paint is a Great DIY Project

Taking on the task of painting fairings with spray paint is one of the most rewarding projects for a garage tinkerer. It allows you to refresh an older bike or change the aesthetic of a track bike without the massive overhead of a professional body shop.

Modern aerosol technology has come a long way, with specialized nozzles that mimic the spray pattern of professional equipment. This means you can achieve a level of atomization—how fine the paint mist is—that was previously impossible with standard hardware store cans.

Beyond the cost savings, doing this yourself gives you total control over the quality. You can spend the extra hour wet sanding a stubborn corner or ensuring the primer is perfectly level, steps that a commercial shop might rush through to stay on schedule.

Essential Tools and Materials for the Job

Before you press that nozzle, you need to gather a specific set of supplies. Using the wrong type of paint on flexible plastic fairings is the number one reason for project failure, so do not cut corners here.

  • Wax and Grease Remover: This is a chemical cleaner that removes road grime, oils, and old wax that would otherwise cause “fish eyes” in your paint.
  • Sandpaper Assortment: You will need 400, 600, and 800 grit for preparation, and 1500 to 3000 grit for final finishing.
  • Plastic Adhesion Promoter: This clear primer helps the paint “bite” into the plastic surface, preventing peeling.
  • High-Quality Primer: A high-build primer is best for filling in minor scratches or imperfections.
  • Base Coat Color: Choose an automotive-grade spray paint designed for plastics or metals.
  • 2K Clear Coat: This is a two-component paint that features a hardener; it is the only way to get a gas-resistant finish.

You should also invest in a quality respirator with organic vapor cartridges. Spraying paint releases volatile organic compounds (VOCs) that are harmful to breathe, especially in a closed garage environment.

Preparing the Surface: The Secret to Success

The quality of your finish is 90% preparation and only 10% the actual spraying. If you spray over a dirty or poorly sanded surface, the new paint will eventually flake off or reveal every tiny scratch underneath.

Begin by washing the fairings with warm, soapy water to remove heavy dirt. Once dry, use a lint-free cloth soaked in wax and grease remover to wipe down every square inch of the plastic.

If your fairings have deep scratches or cracks, now is the time to fix them. You can use a plastic welder or a specialized flexible body filler to smooth out the gouges before you begin the sanding process.

The Sanding Progression

Start with 400-grit sandpaper to scuff the entire surface of the existing paint or raw plastic. You aren’t trying to remove all the old paint; you just want to remove the gloss so the new layers have something to grip.

Use a “wet sanding” technique by keeping the paper and the fairing wet with a spray bottle. This prevents the sandpaper from clogging and creates a much smoother surface than dry sanding.

Once the surface looks dull and uniform, rinse it thoroughly and dry it. Any shiny spots you see are areas where the paint might not stick, so go back and hit those spots again until everything is matte.

Applying Primer and the Base Coat

Now that the fairing is clean and scuffed, it is time to start the chemical bond. If you are working with raw plastic, apply two light coats of adhesion promoter and wait about 10 minutes between them.

Follow this with your high-build primer. Apply the primer in thin, even passes, overlapping each stroke by about 50%. Do not try to get full coverage on the first pass; it should look a bit transparent at first.

Sanding the Primer

After the primer has cured—usually about 2 to 4 hours depending on the temperature—lightly sand it with 600-grit wet sandpaper. This step ensures that the base color sits on a perfectly flat foundation.

Wipe the surface down with a tack cloth right before you start the color coat. A tack cloth is a sticky cheesecloth that picks up tiny dust particles that your eyes might miss.

Apply the color base coat in three stages. The first is a “tack coat” (very light), the second is a medium coat, and the third is a slightly heavier coat to bring out the true depth of the color.

Achieving a Mirror Finish with 2K Clear Coat

The clear coat is what provides the shine and the protection. When painting fairings with spray paint, using a standard 1K clear coat from a big-box store is a mistake because it will dissolve if you spill a drop of gasoline on it.

A 2K clear coat comes in a specialized can with a button on the bottom that releases a catalyst. Once activated, you have a limited “pot life” (usually 24 to 48 hours) to use the entire can before it hardens inside.

Apply the clear coat in two to three wet coats. A “wet coat” means you spray just enough paint so the surface looks glossy and liquid, but not so much that it starts to run or sag down the fairing.

Wait about 10 to 15 minutes between coats of clear. This allows the solvents to flash off, preventing bubbles from being trapped under the next layer, which causes a cloudy appearance.

Common Mistakes and How to Fix Them

Even experienced DIYers run into issues when painting fairings with spray paint. The key is knowing how to react when something goes wrong instead of panicking and making it worse.

Dealing with Paint Runs

If you see a “run” or a “curtain” of paint forming, do not touch it while it is wet. You will only make a massive smear that is much harder to fix later.

Let the paint dry completely for at least 24 hours. Once hard, you can use a sanding block with 800-grit paper to carefully level the run until it is flush with the rest of the surface, then re-spray.

Avoiding Orange Peel

Orange peel is a bumpy texture that looks like the skin of an orange. It usually happens because the spray can was held too far away, or the temperature was too high, causing the paint to dry before it could level out.

You can fix orange peel after the clear coat has fully cured by wet sanding with 2000-grit paper and then using a high-speed buffer with polishing compound to restore the shine.

Workshop Safety and Environmental Factors

Your workshop environment plays a massive role in the final result. Humidity is the enemy of spray paint; if it is over 60%, the moisture can get trapped in the paint, causing a “blush” or white haze.

Always ensure you have plenty of cross-ventilation. If you are working in a garage, open the door slightly and use an exhaust fan to pull the fumes away from your face and out of the building.

Keep a fire extinguisher nearby. Most aerosol paints are highly flammable, and the fine mist can be ignited by a pilot light on a water heater or a stray spark from a grinder.

Protecting Your Surroundings

Overspray travels much further than you think. If you are painting in a garage with a car or other tools nearby, cover everything with plastic drop cloths or old bedsheets.

The fine mist from painting fairings with spray paint can settle on surfaces twenty feet away, leaving a gritty residue that is incredibly difficult to remove once it dries.

Frequently Asked Questions About Painting Fairings with Spray Paint

How long should I let the paint dry before putting the fairings back on the bike?

While the paint might feel dry to the touch in an hour, it takes much longer to fully “outgas” and harden. Wait at least 48 to 72 hours before handling the parts or bolting them back onto the motorcycle frame.

Can I paint over the original factory stickers?

It is highly recommended to remove all decals before painting. If you paint over them, the edges of the stickers will show through as a visible ridge, and the adhesive may eventually fail, causing the new paint to bubble.

What temperature is best for spray painting?

The ideal temperature range is between 65°F and 85°F (18°C to 29°C). If it is too cold, the paint won’t flow properly; if it is too hot, it will dry in the air before it hits the fairing, creating a rough texture.

Do I really need to use a 2K clear coat?

Yes, especially for motorcycle fairings. Standard spray paint clear coats are not resistant to chemicals. If you spill fuel while filling your tank, a 1K clear coat will soften and peel immediately, ruining your hard work.

Final Thoughts for the DIY Painter

Mastering the art of painting fairings with spray paint is a journey of patience and attention to detail. It is one of those skills where you truly get out what you put in; the more time you spend on the boring sanding stages, the more spectacular the final reveal will be.

Don’t be discouraged if your first attempt isn’t perfect. Paint is forgiving because you can almost always sand it back down and try again. The confidence you gain from successfully refinishing your own motorcycle parts will spill over into other areas of your workshop life.

Grab your respirator, set up your workspace, and take that first step. With a steady hand and a bit of “elbow grease,” you’ll have a bike that looks like it just rolled off the showroom floor, all for the price of a few high-quality cans of paint.
