Plastic items are prone to fading due to various factors, primarily UV exposure, which causes colour fading and material breakdown. Other factors include oxidation, which results in a rougher texture, and the use of bromine, which causes plastic to change colour over time. To prevent plastic from fading, it is essential to protect it from these elements. This can be achieved through the use of UV-resistant sealants, storing items away from direct sunlight, and choosing plastic products with fade-resistant solutions. Additionally, commercial products such as Meguiar's Ultimate Black and Armor All can help restore faded plastic and provide temporary protection. For car owners, parking in covered areas or using windshield sunshades can help prevent interior plastic damage.

What You'll Learn
Store plastic items away from direct sunlight
Sun exposure is a major cause of plastic fading. The ultraviolet (UV) rays from the sun cause discolouration and material breakdown. Therefore, storing plastic items away from direct sunlight is a simple yet effective way to prevent fading.
For indoor plastic items, avoid placing them near windows or glass doors where sunlight streams in. Instead, opt for shaded areas of the room. If possible, use curtains or blinds to block out direct sunlight during peak hours. For items that are used outdoors, such as patio chairs, garden tools, or plastic containers, store them in shaded areas when not in use. You can also use structures like garages or sheds to keep them out of direct sunlight.
For plastic items in your car, such as the dashboard, steering wheel, or interior trim, parking in covered areas like garages or under shade trees can provide protection. Additionally, using windshield sunshades will help block direct sunlight from entering the car and reduce UV exposure. If you need to park in an open area, consider investing in a car cover that shields the vehicle from direct sunlight.
Even indirect sunlight can cause plastic to fade over time, so maintaining consistent storage habits is crucial. By storing your plastic items away from direct sunlight, you can significantly slow down the fading process and maintain their appearance for a longer period.

Apply a UV-resistant sealant
UV rays are the main cause of colour fading and material breakdown in plastic. To prevent this, you can apply a UV-resistant sealant. These products form a protective barrier that blocks ultraviolet rays and helps lock in colour and moisture.
There are several products available that can provide this protective barrier, including Graphene VRT and 303 Aerospace Protectant. These products are ideal for car trim, outdoor furniture, and plastic decor. When applying these products, use a microfiber cloth on clean, dry surfaces.
You should reapply the sealant every few months, depending on exposure and product instructions. For example, if your plastic item is exposed to direct sunlight for long periods, you may need to reapply the sealant more frequently.
When choosing a UV-resistant sealant, look for products labelled "UV protection" or "ceramic-based" for the best results. These sealants will provide a protective barrier that blocks UV rays and slows down the fading process.
By taking these simple steps and applying a UV-resistant sealant, you can effectively protect your plastic items from fading and maintain their original appearance.

Use a heat gun to restore colour
Using a heat gun is an effective way to restore the colour of faded plastic. This method works by slowly breaking down the plastic's molecular composition, allowing the chemical bond to realign as the polymers cool, leaving a wet, glossy surface.
To use a heat gun to restore the colour of plastic, start by cleaning the surface of any waxes or treatments, as these can react negatively to the heat. Next, plug in your heat gun and set it to its lowest heat setting. Hold the heat gun 4-6 inches away from the plastic surface and turn on the heat. Keep the heat gun moving at all times to avoid applying too much heat to one spot and causing the plastic to melt. You should see spots begin to appear on the plastic, which is called "sweating". As you move the heat gun in a concentric pattern around the area, you will see the sweating increase, and the colour will gradually deepen and return to its original richness. Once the plastic has cooled, you can apply a coat of protectant, such as Meguiar's Ultimate Black plastic restorer, to the surface.
It is important to note that this process is temporary, as the oils in the plastic will eventually dry out and the colour will fade again. Additionally, each time you use a heat gun on plastic, it becomes more brittle and prone to cracking and breaking. Therefore, it is recommended to use this method sparingly and only when other remedies have been exhausted.
Some alternative methods for restoring colour to faded plastic include using chemical dressings, such as Solution Finish or Autoglym Bumper and Trim Gel, or applying a coat of paint.

Use commercial restoration products
Commercial restoration products are a great option for restoring faded plastic and preventing further damage. These products typically fall into three categories: dressings, restoration products, and coatings/protection.
Restoration products work by replenishing the oil and pigment lost from the plastic due to UV and chemical exposure. For example, Meguiar's Ultimate Black is a trusted name in car care and is designed to restore and maintain exterior plastic and rubber trim. It provides a dark, glossy finish and includes UV protection to prevent future fading. It is easy to find in stores and can be easily applied by wiping it on. However, it may wear off in heavy rain or after a few car washes.
Another option is to use a product like Solution Finish, which can be sprayed onto the plastic. Tape off any paint around the plastic and spray it like you would spray paint. Apply a second coat after 15 minutes. Solution Finish provides a long-lasting stain that beads water and does not wash off.
For a more permanent solution, you may need to respray or re-paint the plastic. This can be an inexpensive process that involves re-painting the plastic using the same paints used in the factory.
In addition to restoration products, you can also use a UV-resistant sealant to protect the plastic from sun damage. Products like Graphene VRT or 303 Aerospace Protectant form a protective barrier that blocks ultraviolet rays and helps lock in color and moisture. Apply these products with a microfiber cloth on clean, dry surfaces and reapply every few months, depending on exposure and product instructions.
By using a combination of restoration products and UV-resistant sealants, you can effectively restore and protect your plastic items from fading.

Preventative manufacturing treatments
One of the most common causes of plastic fading is exposure to UV rays, which break down the material and cause discolouration. Therefore, one of the most effective preventative treatments is to apply a UV-resistant sealant to the plastic. These sealants form a protective barrier that blocks UV rays and helps lock in colour and moisture. Manufacturers can apply such sealants, labelled "UV protection" or "ceramic-based", to products like car trim, outdoor furniture, and plastic decor. Reapplication may be required every few months, depending on the product's exposure to sunlight and specific instructions.
Another preventative treatment is to use anti-UV additives during the manufacturing process. These additives are designed to boost the durability and longevity of plastic products under harsh sunlight and weather conditions. By incorporating these additives into the plastic formulation, manufacturers can create products that are more resistant to fading, discolouration, and material breakdown.
Additionally, some products can restore the oils and pigments missing from plastic due to UV and chemical exposure. These restoration products can be applied to severely faded or oxidised black trim, providing a long-lasting deep restoration effect.
Manufacturers can also explore creating fade-resistant plastic solutions, which are specifically engineered to withstand time, UV exposure, and wear. These solutions can help maintain vibrant colours and surface integrity over time, ensuring that plastic products remain protected from fading.
