Plastic door panels can be repaired and restored in a variety of ways. One common issue is cloudy plastic, which can be buffed out with toothpaste or fine-grit sandpaper. Alternatively, acetone or plastic polish can be used. When it comes to attaching plastic sheeting to the inside of a door panel, adhesive products can be used. It is important to ensure that the adhesive is properly installed and maintained to prevent leaks. In some cases, it may be necessary to replace the plastic inside the door. This can be done by temporarily removing the inner vinyl skin and applying boiled linseed oil to both sides of the paperboard before reattaching the vinyl covering. Additionally, hosing down the locking mechanism and sheet metal with spray lube and rust protectant can help prevent door rust.

What You'll Learn
Cleaning door plastic with toothpaste, sandpaper, acetone, or plastic polish
When it comes to cleaning door plastic, there are a few different methods you can use, each with its own advantages and considerations. Here is a detailed guide on how to clean door plastic using toothpaste, sandpaper, acetone, or plastic polish:
Toothpaste
Toothpaste is a surprisingly effective and gentle cleaner for door plastic. Its mild abrasive properties can help buff out micro-abrasions and light scratches without causing damage. Simply apply a small amount of toothpaste to a damp cloth and gently rub it onto the affected areas of the door plastic in a circular motion. Then, rinse the area with water and dry it with a soft cloth. It is important to test the toothpaste on an inconspicuous area first to ensure it does not cause any discolouration or damage to the plastic.
Sandpaper
While sandpaper can be effective in removing more stubborn scratches and abrasions from door plastic, it requires extreme caution. It is crucial to use only fine-grit sandpaper and apply gentle pressure to avoid creating deeper scratches or damaging the plastic. Always sand in the direction of the scratch, and never use coarse-grit sandpaper, as it can cause more harm than good. As with any new technique, test it on an inconspicuous area first.
Acetone
Acetone is a strong solvent that should generally be avoided when cleaning door plastic. It can quickly dissolve and damage the plastic, leaving it worse off than before. If you decide to use acetone, exercise extreme caution and always follow the instructions on the product label. Never use acetone on painted plastic surfaces, as it will remove the paint along with the finish.
Plastic Polish
Plastic polish is a purpose-made product designed to clean and restore the shine to door plastic. It is available in various forms, such as PlastX polish, Semichrome polish, and Polywatch. These polishes typically contain a mix of mild abrasives and solvents, which effectively remove scratches and leave a glossy finish. Follow the instructions on the product and always test it on an inconspicuous area first to ensure compatibility with your door plastic.
Remember, when cleaning door plastic, it is essential to work gently and test any new products or techniques on a small, inconspicuous area first to prevent unintended damage. Always read and follow the safety instructions on any cleaning products you use.

Using boiled linseed oil to waterproof door panels
Boiled linseed oil is a penetrating oil finish that can be used to treat wood and metal. It is a popular choice for those seeking a warmer shade for their wooden surfaces.
When using boiled linseed oil to treat door panels, it is important to note that it is not necessary to apply a film-finish topcoat. The oil will never need to be refinished, and if it starts looking dull over time, it can be scuffed up with a scotch brite pad and more oil can be applied.
However, boiled linseed oil takes a long time to dry and cure, and it is susceptible to staying sticky or not drying at all if applied too thickly, onto damp materials, or in cold temperatures. Thinning the oil with turpentine can help, but it is still important to apply thin coats and allow each coat to dry before applying the next.
Additionally, boiled linseed oil does not provide UV protection and can encourage mildew growth. Therefore, it is important to consider the environment in which the door panels will be placed and whether they will be exposed to UV light or moisture, which could impact the oil's effectiveness as a preservative.
Overall, boiled linseed oil can be an effective treatment for door panels, providing a warm and natural finish, but it is important to consider the potential drawbacks and lengthy drying time.

Applying rust protectant to door panels
To prevent rust from forming on your door panels, there are several methods you can use. Firstly, it is important to understand that rust is a natural reaction that occurs due to exposure to oxygen, carbon dioxide, and moisture. Therefore, to prevent rust, you need to create a protective barrier against these elements.
One popular method is to use a cavity wax injection, which involves spraying a rust-inhibiting, waterproof, waxy solution inside every box section of your vehicle. This solution has self-healing properties, so if it gets scratched, it will reseal the affected area. Additionally, the rust-inhibiting molecules cling actively to the metal surfaces.
Another option is to use a hard coating, which can be effective for new vehicles with no existing rust. You can also use rust-preventive paints with zinc to prevent future rust and keep your doors looking great.
If you are looking for a quick fix, you can try using a spray-on rust preventer or a product like WD-40. For more severe cases of rust, you may need to use a rust remover chemical, vinegar, or a paste made of baking soda and water. After applying the paste, wait for about 30 minutes, then use a soft cloth to remove it.
Remember, the best method for rust prevention depends on the severity of the rust and the type of surface you are treating. Always follow the instructions on any products you use, and consider seeking professional advice if you are unsure.

Using spray adhesives to attach plastic sheeting to door panels
When using spray adhesives to attach plastic sheeting to door panels, it's important to select an appropriate adhesive that will create a strong bond while also allowing for future removability and reattachment if needed. This is especially important in car door panels, where water leakage can occur if the adhesive is not properly sealed or deteriorates over time.
Before applying any adhesive, ensure that the surfaces are clean, dry, and free of debris. If you're working with car doors, it's crucial to address any leaks or water damage before reattaching the plastic sheeting. This may involve scraping away old adhesive residue and ensuring the door panel is thoroughly dry.
There are several spray adhesives recommended for attaching plastic sheeting to door panels. One option is to use a product like 3M Spray Foam 74, which can be applied to both surfaces and allowed to dry before sticking them together. Another option is to use a headliner adhesive, such as the 3M Headliner Adhesive or Mercedes headliner glue, which is designed for bonding materials like leather to panel boards. These adhesives are often used by professionals in automotive upholstery applications.
When working with spray adhesives, always follow the manufacturer's instructions and safety guidelines. Wear protective gear, such as gloves and a respirator, and ensure adequate ventilation during application. Apply the adhesive evenly and sparingly to avoid oversaturation. Once the adhesive is applied, carefully align and position the plastic sheeting onto the door panel, pressing and holding it in place according to the adhesive's recommended curing time.
It's important to note that some adhesives may require specific surface preparations or curing conditions, so always refer to the product instructions. Additionally, consider using a protective coating or sealant on the edges of the plastic sheeting to prevent water ingress and ensure a long-lasting bond.

Removing plastic barriers from doors during power window conversion
Removing the plastic barriers from doors during a power window conversion can be a tedious task, but it is doable with the right tools and techniques. Here is a step-by-step guide to help you through the process:
Step 1: Understand the Purpose of the Plastic Barrier
Before removing the plastic barrier, it is essential to understand its purpose. The plastic barrier, also known as a moisture barrier, is typically installed by the factory to protect the door card from moisture and, to a lesser extent, provide sound insulation. Understanding its function will help you determine the best approach for removal and replacement.
Step 2: Disassemble the Door Panel
To access the plastic barrier, you will need to carefully disassemble the door panel. This process may vary depending on your vehicle's specific make and model. Take your time and be gentle to avoid damaging any other components or the door itself. You may need to remove screws, clips, or other fasteners holding the door panel in place.
Step 3: Locate the Plastic Barrier
Once the door panel is removed, you will be able to see the plastic barrier. It is usually located between the door and the door panel, often secured with an adhesive. The barrier may be transparent or have a bluish colour, as in the case of Suzuki part #83911-60X51, and may need to be cut to fit your door.
Step 4: Remove the Old Plastic Barrier
This step can be tricky, as you need to carefully detach the plastic barrier from the door without causing damage. Start by peeling or scraping away the adhesive strip that secures the barrier in place. You can use a plastic or metal scraper, being careful not to scratch the door. If the adhesive is stubborn, you may need to use a solvent like WD40 or a gel-type paint stripper. However, be cautious when using solvents, as they can damage other components, such as the window frame or primer.
Step 5: Clean and Prepare the Surface
After removing the old plastic barrier and adhesive, clean the surface thoroughly. Make sure there is no residue left, as it can affect the adhesion of the new barrier. You may use a degreaser or a mild solvent for this step, but always test it on a small area first to ensure it doesn't damage the door material.
Step 6: Install the New Plastic Barrier
Finally, install the new plastic barrier. You can use a thicker vinyl material and secure it with black putty strips between the metal door and the plastic. Use a small roller to flatten the putty and ensure a strong bond. Make sure the new barrier is cut to fit your door properly, and consider using fasteners or clips for added security.
Remember to take your time during the process and work carefully to avoid damage. Always wear the appropriate safety gear, such as gloves and eye protection, when handling chemicals or sharp tools.
