Wet sanding products and tools

Wet sanding is a process that can help restore the shine to your ATV's plastic components. It involves sanding down the plastic with sandpaper and water to remove scratches and other imperfections. This process can be done by hand or with a powered sander, and it requires a few specific products and tools to achieve the best results.

The first step is to gather the necessary supplies, which include various grits of sandpaper, a sanding block or pad, a bucket of water, a towel, and some plastic cleaner. It is important to use the correct type of sandpaper for wet sanding, as regular sandpaper may disintegrate when it gets wet. Wet sanding sandpaper is typically made with a waterproof backing that can withstand repeated exposure to water without falling apart. It is also flexible, allowing it to conform to the curves of your ATV's plastic. This type of sandpaper is available in a range of grits, from coarse to ultra-fine, and can be purchased from auto parts stores, Walmart, or online retailers like Amazon.

In addition to sandpaper, you will also need a sanding block or pad to attach the sandpaper to. This provides a comfortable grip and allows you to apply even pressure during the sanding process. Some sanding blocks are specifically designed for wet sanding, with features such as precision flat surfaces and edges that prevent glue residue from being left behind on the plastic. These blocks can be found at specialty auto body suppliers like Linear Blocking Tools.

To get started, you will also need a bucket of water to keep your sandpaper and the plastic surface wet during sanding. This helps to prevent scratching and melting of the plastic. A towel is also useful for drying off the ATV after wet sanding. Finally, a plastic cleaner or plastic renew product can be used to remove any remaining dirt or grease and restore shine to the plastic.

With these products and tools, you can effectively wet sand your ATV's plastic, removing scratches and bringing it back to life.

Sanding techniques

Wet sanding is an effective technique to restore the shine and uniformity of ATV plastic surfaces. It involves using sandpaper to smoothen out scratches and imperfections, followed by buffing or polishing to enhance the shine. Here are some detailed sanding techniques to guide you through the process:

Start with a clean surface: Before beginning the sanding process, ensure that your ATV plastic is thoroughly cleaned. Use warm soapy water and a towel to remove any dirt, grease, or residue. This step is crucial as it ensures that you are working on a smooth surface, and it helps prevent the sandpaper from clogging.

Choose the right sandpaper grit: The grit of the sandpaper you choose depends on the depth of the scratches you want to address. For deep scratches, start with a coarser grit, such as 180, 220, or 320. As you progress and the deeper scratches are removed, move to finer grits like 400, 600, and 1000. The finer grits will help refine the scratches left by the coarser paper and create a smoother finish.

Wet the sandpaper: Wet sanding plastic requires the use of water to lubricate and cool the surface. Soak the sandpaper in a bucket of water for at least 15 minutes, or even overnight, to ensure it is thoroughly saturated. Keep the sandpaper and the plastic surface wet throughout the sanding process. Dip the sandpaper in water frequently to maintain adequate lubrication.

Sand in irregular motions: When sanding, avoid repeating the same path or motion. Use irregular or circular motions to prevent creating deep scratches or grooves in the plastic. Work in one direction with coarse grits to avoid a whirlwind of scratches. If you're sanding a broad, flat section, consider using a foam block to help guide your movements and prevent uneven sanding.

Address deep scratches first: Focus on the deeper scratches first before moving on to the nicer parts of the plastic. Run water over the sanded area to magnify the scratches and identify areas that require more attention. Deep scratches will usually appear shiny when the plastic is dried, making them easier to spot.

Progress through grits: As you work through the different grits, gradually refine the sanding process. With finer grits, sand slightly off the grain or at a slight angle to the plastic surface. This will help create an even finish and remove the scratches left by the previous grit. Remember to keep the sandpaper and surface wet during this entire process.

By following these sanding techniques and progressing through the different grits, you will be able to effectively smoothen out scratches and create a uniform surface on your ATV plastic. Remember to take your time, work in well-ventilated areas, and wear the appropriate protective gear, including gloves and eye protection.

Removing scratches

Wet sanding is an effective way to remove scratches from ATV plastic. It is important to note that the process of removing scratches from ATV plastic requires patience and attention to detail. Here is a step-by-step guide:

Prepare the ATV Plastic:

Start by ensuring the plastic surface is very clean. Wash it with warm soapy water and towel dry. It is crucial to remove any dirt, grease, or residue before beginning the sanding process.

Choose the Right Sandpaper Grit:

The grit of the sandpaper you choose depends on the depth of the scratches. For deep scratches, start with a coarse grit such as 180, 220, or 320. For finer scratches, you can start with a higher grit, such as 400 or 600. If you are unsure, it is recommended to start with a coarser grit and work your way up.

Wet the Sandpaper:

Wet sanding requires the sandpaper to be soaked in water. Submerge the sandpaper in a bucket of water for at least 15 minutes, or even overnight, to ensure it is fully saturated. Keep the sandpaper and the plastic surface wet throughout the sanding process.

Sanding Technique:

When sanding, use irregular motions to avoid creating new deep scratches. A circular motion is recommended, but be sure not to repeat the same path. Work on the deeper scratches first, using a light touch and maintaining the sandpaper in one direction. For broader, flatter sections of plastic, consider using a foam block to assist in the sanding process.

Progress Through Grits:

As you work through the different grits of sandpaper, you will notice the scratches becoming less visible. Once the deep scratches are addressed, move on to the next finer grit. Keep the paper and plastic wet, and check the paper often to ensure it is not causing new scratches.

Final Steps:

After sanding with the finest grit, such as 600 or 1000, dry off the plastic completely. At this stage, you may notice that the plastic still looks foggy or faded. This is where products like plastic renewers, liquid rubbing compounds, liquid wax, and buffers come into play. These products will help restore the shine and uniformity of the plastic surface.

It is important to note that some people opt for alternative methods, such as using heat or a hair dryer, to restore the shine of ATV plastic. However, these methods should be approached with caution as they can potentially damage the plastic. Additionally, products like plastic restore kits, vinyl graphics, and power polishers can also be used to enhance the appearance of ATV plastic.

Buffing and polishing

First, ensure your plastic is clean. Wash the plastic with a mild cleanser, soap, and warm water to remove any dirt and debris. Dry with a towel.

Next, you can buff out any remaining scratches. Toothpaste, baking soda, or sandpaper can be used to buff out scratches. If using sandpaper, start with a fine-grained sandpaper and work your way up to a coarser grit if the scratches are not buffing out. Keep the sandpaper wet at all times and sand in a circular motion to avoid creating lines.

Finally, you can use a polishing compound or a buffing wheel to restore shine to the plastic. Metal polish can also be used to achieve a glossy sheen. Apply the polish with a soft, clean cloth in small, circular motions.

Alternative methods

There are several alternative methods to wet sanding ATV plastic. Firstly, if you are dealing with just a few spots, you can use heat by lightly going over the area with a propane torch. If the areas are large, you will need to lightly sand all the plastic to match, then go over it with 000 steel wool, and then use a product like Green Glo or Plastic Renew. You can also use car wax and a heat gun, which works very well. The heat will close the cells of the plastic, making it less prone to hold dirt particles and increasing shine.

Another alternative method is to use a buffing wheel in your die grinder and some plastic buffing compound for the final step. You can also use toothpaste, baking soda, or vinegar for wet sanding plastic, but be sure to wear gloves and prepare your work area accordingly. Additionally, if you are applying paint to your plastic surface, you can wet sand the primer before any base coat goes down.

If you are looking to achieve a shiny finish, you can use a product called Plastic Renew, which is supposed to work well. You can also pick up a bottle of plastic cleaner, specifically designed for cleaning the plastic on Lexan headlights found on newer cars. Spend some time working it in, as it will take a while. Finally, when you are done with that, you can use a product like High Gloss SC1 Clear Coat from Maxima Oils.
