Painting letters on snowmobile plastic requires a few steps to ensure the paint adheres well and looks good. First, the plastic must be cleaned thoroughly and any rough spots must be scrubbed with a sponge or sanded with light sandpaper. Then, the plastic should be washed again to ensure it is free of any dirt or dust. Once the plastic is completely dry, it can be painted with a spray paint specifically designed for plastic, such as Krylon Fusion. It is important to hold the can at least 8 inches away from the plastic and to move across the plastic at a steady pace to avoid globs of paint building up. Multiple coats of paint may be necessary to achieve the desired colour and coverage.

What You'll Learn
Prepping the plastic surface
Firstly, remove the plastic panels from the machine. This will allow you to work on them more easily and access all areas for cleaning and painting. Once removed, give the panels a thorough wash. Use hot soap and water, and scrub them with a sponge to remove any dirt, grime, or scuff marks. Pay extra attention to any rough spots that may need a deeper clean.
After washing, you may need to use a light sandpaper to smooth out any damaged areas. Start with a finer grit sandpaper, such as 400, and gradually increase the grit size if needed. This process will help create a smoother surface for the paint to adhere to. It is important to note that while some sources recommend sanding, others suggest that certain types of paint, like Krylon Fusion Spray paint, do not require any sanding or priming beforehand.
Once the panels are clean and smooth, it's essential to remove any remaining dust or residue. Use a wax and grease remover, ensuring you wipe the panels thoroughly until they are completely dry. You can also use an evaporating solvent that is safe for plastic to ensure no residue is left behind. Additionally, you can use a spray glass cleaner for your final wipe-down to eliminate any static electricity.
Before painting, it is crucial to ensure the panels are completely dry and free of any dust or bugs. Place them in a clean area, such as on a sawhorse, and make sure they are well-spaced to avoid any overspray issues. It is also important to note that the paint you choose should be specifically designed for use on plastic surfaces.
By following these steps, you'll be able to properly prep the plastic surface of your snowmobile, ensuring a smooth base for painting and helping the paint adhere strongly and last longer. Remember, taking your time with the preparation process will yield better results in the end.

Choosing the right paint
Painting letters on snowmobile plastic requires careful preparation and the right paint. The paint you choose will depend on the finish you want, the colour, and the amount of time and money you want to spend on the project.
Krylon Fusion Spray paint is recommended by some sources as the best paint for plastic. It is available at Sears and requires no prep work (sanding or priming), and the paint adheres well. However, it is only available in basic colours. Pactra Paint, available at hobby stores, is another option that works well on plastic.
If you are looking for a wider range of colours, you can visit a local auto paint store, where they can make almost any colour in an aerosol can. Ask about a knockoff brand to find a more affordable option.
For a gloss finish, you can use Plastydip, which requires about six thin coats (three to four are recommended). The benefit of Plastydip is that if you don't like the result, you can peel it off.
If you are painting a snowmobile hood, some sources recommend using a flex additive to keep the paint soft and flexible, especially if you are assembling parts with plastic bumpers. However, this may only last a week or two once the paint is cured.
For a top-notch finish, it is recommended to have a body shop paint your snowmobile plastic. While this option is more expensive, it will result in a higher-quality, longer-lasting paint job.

Painting technique
Firstly, it is important to prepare the surface of the snowmobile plastic that you will be painting on. Remove the panels from the machine and give them a thorough wash, scrubbing any rough spots with a sponge. If the panels have been damaged, you may need to use light sandpaper to smooth them out. It is recommended to use 400-grit sandpaper and then 800-grit sandpaper to get the desired smoothness. This preparation step is crucial to ensure the paint adheres well and the final product looks neat.
Once the panels are smooth, give them another wash to ensure they are free of any dust, dirt, or grime. Choose a paint that is specifically designed for plastic surfaces. Krylon Fusion Spray Paint is a popular choice and can be found at Sears. It requires no prep work and adheres well to plastic. However, it is only available in basic colours. If you want a custom colour, you may need to explore other paint options or consider getting the panels professionally painted.
Before painting, ensure the panels are completely dry. Place them in an area that is free of bugs, dust, and dirt, and where you can easily access all angles of the panels. Hold the paint can at least 8 inches away from the surface and start spraying in sweeping motions. Do not point the can directly at the plastic; instead, start about 3-4 inches away and work your way across the surface. Move at a steady pace, not too fast and not too slow, to avoid paint build-up and ensure an even coat.
After the first coat, let the panels dry for about 5 minutes. Apply a second coat, and you should still be able to see the base plastic colour. Let the panels sit for another 5 minutes, and then apply a third coat from a different angle to ensure complete coverage. Repeat this process until you have applied at least four coats of paint. After the fourth coat, let the panels sit for at least 15 minutes before applying additional coats or moving on to the next step.
To add a professional touch and protect your paint job, consider applying a clear coat sealer. This will give the surface a smooth finish and enhance the paint's integrity. You can find clear coat sealers at your local auto paint store or online. Remember to follow the specific instructions on your chosen product for the best results.

Drying and curing
After you've finished painting, it's crucial to allow sufficient drying time before moving on to the next steps. The drying time will depend on the type of paint you've used and the number of coats applied. For example, if you're using a spray paint like Krylon Fusion, which is specifically designed for plastic, follow the manufacturer's instructions for drying times. Typically, you'll need to let each coat dry for a specified duration before applying the next one.
In general, it's recommended to let the first coat of paint dry for about 5 minutes. Then, apply subsequent coats, allowing for drying time between each application. After you've completed all the coats, the panels will need to sit for a more extended period. For instance, some users suggest letting the panels sit for at least 15 minutes after the final coat. This extended drying time ensures that the paint has adequately cured and hardened.
In addition to time, environmental factors play a role in drying and curing. Ensure that the painted panels are kept in a dust-free, bug-free, and dirt-free environment during the entire drying and curing process. Any contaminants that settle on the paint during this period can ruin your work. Placing the panels in a controlled environment, such as a dust-free room or a covered outdoor area, can help prevent this.
Once the paint has dried to the touch, it's essential to understand that it's not yet fully cured. The curing process for plastic paints can take several days to weeks, depending on the type of paint and the environmental conditions. During this period, the paint continues to harden and reach its maximum durability. Avoid exposing the painted letters to excessive handling, abrasion, or harsh weather conditions until the curing process is complete.
To accelerate the curing process, consider using a clear coat sealer specifically designed for plastic surfaces. A clear coat can provide a smooth finish and enhance the integrity of the paint. Additionally, it can act as a protective layer, shielding the paint from the elements and prolonging its lifespan. However, always follow the manufacturer's instructions for applying a clear coat, as improper application may lead to undesirable results.

Finishing and sealing
Once you have painted your snowmobile plastic, it is important to finish and seal it properly to ensure the paint job is durable and long-lasting. Here are the steps you should follow:
Firstly, after painting, let the pieces dry for at least 15 minutes, as recommended by one source. Another source suggests leaving it for 20-30 minutes. This will allow the paint to cure and harden. It is important to be patient during this step, as impatience can lead to smudging or accidental removal of the paint.
After the paint has cured, you can apply a clear coat or sealant. This step is crucial, as it will protect the paint from chipping, peeling, or scratching. There are a variety of sealants available, including a clear coat sealer, a flex additive, or a urethane sealer. You can also use a product like Krylon Fusion Clear Coat, which is designed to work with spray paint and provide a smooth finish.
When applying the sealant, follow the manufacturer's instructions carefully. Typically, you will need to spray or brush on a thin, even coat. Make sure to cover all painted areas, and be cautious of over-application, which can cause drips or sags. Allow the sealant to dry completely according to the product's instructions.
Once the sealant is dry, you may need to apply a second coat for added protection. Follow the same application process, and allow it to dry. After the final coat of sealant has cured, your snowmobile plastic should have a durable and long-lasting finish.
It is worth noting that some sources suggest that even with proper finishing and sealing, paint on snowmobile plastics may still chip or peel over time. This is due to the flexible nature of the plastic and the constant vibration and movement of the snowmobile. However, following the above steps will give your paint job the best chance of lasting for multiple seasons.
