What You'll Learn
Use a chemical process
While there are a variety of methods to restore a white plastic gas tank, some of the most effective ways involve using chemicals. Here is a detailed guide on how to use a chemical process to restore your white plastic gas tank:
Firstly, it is important to note that some chemicals can be too strong and may damage the plastic. It is recommended to avoid using acetone, lacquer thinner, or paint thinner as these can soften or melt the plastic. Instead, opt for milder acids or chemicals that are safe for plastic.
One popular method is to use vinegar. Fill the tank with vinegar and let it soak for some time. The acidic nature of vinegar helps in breaking down the stains and restoring the tank's colour. You can also add some gravel, rocks, or hardware into the vinegar-filled tank and shake it vigorously. Alternatively, you can strap the vinegar-filled tank to the rear wheel of your tractor and let it spin slowly, allowing the vinegar to work its magic while the gravel or rocks tumble inside.
Another chemical process involves using denatured alcohol. Before applying it to the tank, test a small spot on the outside of the tank to ensure it doesn't cause any adverse reactions. If it seems safe, proceed to apply it to the affected areas.
Some people have also suggested using mild acids like battery acid or muriatic acid (hydrochloric acid). However, these chemicals can be hazardous and should be handled with extreme caution. Always wear protective gear and avoid direct contact with skin and eyes.
Additionally, you can try commercial products specifically designed for plastic restoration, such as "Wipe New" or "Kleen." These products have been known to deliver good results and are worth considering if you're looking for a more specialised solution.
Remember, when working with any chemicals, it's important to prioritise safety. Always work in a well-ventilated area, wear protective gear, and follow the instructions and warnings provided by the chemical manufacturers.

Sand the tank
Sanding is a great way to restore a white plastic gas tank. It is a process that can help remove surface discolouration and restore the plastic to its original white colour.
To sand the tank, start by cleaning the tank with a detergent solution. If the tank is especially dirty, a solution of water and vinegar in a 1:1 ratio can be used with a gentle cloth. It is important to ensure that all dirt and residue are removed before sanding.
Next, you will need to choose the right sandpaper for the job. It is recommended to use wet sandpaper to prevent scratches on the plastic surface. The grit of the sandpaper should be between 180 and 600 for the initial sanding. Immerse the sandpaper in water for at least 15 minutes before use, ensuring that the paper itself is saturated.
Now, you can begin the sanding process. Gently rub the sandpaper over the plastic in irregular circular motions, alternating between straight lines. Be sure not to repeat the same path to avoid shaping a valley in the plastic. Spray the tank with water every few minutes to keep the surface wet.
Continue sanding until you have removed all the discolouration and smoothed out any rough spots. Once you are satisfied with the results, wipe down the tank with a wet cloth to remove any remaining dust or residue.
After sanding, it is important to polish the tank to restore shine and protect the surface. A soft buff and a small amount of plastic polish can be used at a slow speed. Be careful not to pause in one spot with the polisher to avoid any damage.

Use a razor blade
Restoring a white plastic gas tank can be a challenging task, but using a razor blade is one of the methods that can help you achieve your desired results. Here is a detailed guide on how to effectively use a razor blade to restore your white plastic gas tank:
First, it is important to understand that the yellowing of the white plastic gas tank is caused by fuel permeating the plastic. This results in discolouration, and simply sanding or scraping might not be enough to remove the staining. However, using a razor blade is a more aggressive approach that can help remove the thin film of discoloured plastic.
When using a razor blade, it is crucial to work with caution and wear protective gear, such as gloves and eye protection. Hold the razor blade firmly and use a flat, smooth motion to scrape away the surface of the plastic. Be gentle and avoid applying too much pressure, as you don't want to scratch or damage the plastic further. Start with a small area and slowly work your way across the entire surface.
After using the razor blade, you might notice that the tank is not perfectly white, but rather a lighter shade of beige. This is normal, and you can further improve the appearance by sanding and polishing. Start with a fine-grit sandpaper, such as 240-grit, and gradually increase the grit size to 1200. Wet sanding is recommended, using a mixture of water and a mild detergent. This process will help smooth out any scratches caused by the razor blade and create an even surface.
Finally, polish the tank using a soft buffing pad and a small amount of plastic polish. Apply the polish with a slow, steady motion, ensuring that you do not focus on one spot for too long to avoid creating uneven marks. This final step will help restore shine and protect the plastic surface.
While using a razor blade can be effective, it is important to note that it may not always achieve a perfect result. The success of this method depends on the severity of the staining and discolouration. Additionally, it is essential to consider safety precautions when working with sharp tools like razor blades. Always prioritize your safety and wear appropriate protective gear.

Apply a plasticoat
While there is limited information on how to apply a Plasticoat, there are a few general steps that can be followed when applying any kind of coating or paint to a plastic surface. Here are some instructive paragraphs specifically focused on applying a Plasticoat to a white plastic gas tank:
Firstly, it is important to prepare the surface of the plastic gas tank. This involves cleaning and drying the surface thoroughly. Use a suitable cloth to wipe down the tank and ensure there is no dirt, grease, or residue left on the plastic. This step is crucial as the Plasticoat will form a separate layer, so a clean surface is essential for optimal results.
Next, you may need to sand the surface of the plastic gently. This step might not be necessary if the tank is already smooth and free of any imperfections. However, if there are scratches or discolouration, use fine-grit sandpaper to gently buff out any imperfections. It is important not to apply too much pressure when sanding, as it may cause more damage.
Once the surface is prepared, it is time to apply the Plasticoat. Ensure you are in a well-ventilated area and follow the instructions on the Plasticoat product carefully. If the Plasticoat is a spray, hold the can at the recommended distance from the surface and apply light, even coats. It is generally better to apply multiple thin coats rather than one heavy coat to avoid dripping or an uneven finish.
After applying the Plasticoat, allow sufficient curing time. Refer to the product instructions for the exact curing time, as it may vary depending on the type of Plasticoat used. During the curing process, avoid any contact with liquids or other substances that may interfere with the curing.
Finally, once the Plasticoat has cured completely, you may need to apply a topcoat or sealant, again following the product instructions. This step will ensure that the Plasticoat is protected and will help it last longer.
By following these general steps and always referring to the specific Plasticoat product instructions, you can effectively apply a Plasticoat to a white plastic gas tank.

Paint the tank
Painting a plastic gas tank can be a tricky process due to the potential for bubbling and peeling. However, with the right preparation and materials, it is possible to achieve a long-lasting finish.
Firstly, it is important to clean the tank thoroughly. This can be done using a combination of soap and water, vinegar, or a mixture of dish soap and comet. It is also crucial to remove any stickers or residue from the surface of the tank. Once the tank is clean, it should be dried thoroughly.
The next step is to prepare the surface of the tank for painting. This typically involves sanding the tank to create a rough surface that will allow the paint to adhere better. The tank should be sanded using progressively finer grit sandpaper, starting with a lower grit such as 180 or 240 and working up to a higher grit like 400 or 600. It is important to take your time during this step and not rush through it, as inadequate sanding can lead to an uneven finish.
Once the tank is sufficiently sanded, it is time to apply a primer. A primer will help the paint adhere better and create a more durable finish. It is recommended to use a high-quality primer and an adhesion promoter to ensure the best results. The primer should be applied in thin, even coats and allowed to dry completely before proceeding to the next step.
After the primer is dry, it is time to start painting. It is important to use a paint that is specifically designed for plastic surfaces, such as plastic-friendly paint or paint designed for automotive use. The paint should be applied in thin, light coats, with multiple coats added to build up the desired coverage and finish. It is important to follow the instructions on the paint can and allow adequate drying time between coats.
Once the final coat of paint has been applied and dried, a clear coat can be added for extra protection and shine. A clear coat, such as PPG clear coat, can provide a strong and hard finish that will protect the paint underneath. Again, it is important to follow the instructions on the product and allow adequate drying time.
By following these steps and taking the time to prepare the surface and choose the right materials, you can successfully paint a white plastic gas tank and achieve a long-lasting and attractive finish.
