Heat guns are a popular tool for restoring faded plastic trim. The technique involves using a heat gun to melt the surface layer of the plastic, which can help to mix the oxidized surface and substrate, releasing the natural oils in the plastic and restoring its colour. This method is temporary, and repeated use will make the plastic more brittle over time, increasing the chances of cracking and breaking. To avoid this, some opt to use products specifically designed for restoring plastic, such as Solution Finish, which can be more effective and long-lasting.

The plastic must be cleaned before using a heat gun
Restoring plastic with a heat gun is an effective method, but it is important to prepare the plastic surface before beginning the process. The plastic must be cleaned thoroughly before applying heat. This is because any dirt, grime, or residue from cleaning products can affect the outcome of the restoration process. For example, years of cleaning products can add to blotchy results.
The plastic should be cleaned with soap and water, and a scrub brush can be used to ensure a thorough clean. A power washer can also be used, but it is important to use a low setting to avoid damaging the plastic. Once the plastic has been cleaned, it should be dried thoroughly before applying heat.
It is also important to note that the heat gun itself should be of good quality. A Porter-Cable gun is a popular choice among those who have successfully restored plastic with a heat gun. A good heat gun will help ensure effective and even heating, which is crucial for achieving the desired results.
Additionally, it is worth mentioning that while heat gun treatment can be effective in restoring plastic, it may not be a long-lasting solution. The plastic may become more brittle with each treatment, increasing the chances of cracking and breaking. Therefore, it is important to consider the condition of the plastic and the potential risks before proceeding with the heat gun restoration process.

Heat guns can be used to remove moisture from plastic
Heat guns are a versatile tool with many applications, including removing moisture from plastic. When plastic is exposed to sunlight, it attracts moisture from the air, and as it cools, the moisture gets trapped in the plastic, causing a cloudy, grey appearance. A heat gun can be used to restore the plastic by opening up the cells and allowing the moisture to escape.
Heat guns are used in many industries, including automotive repair, construction, and electronics. They are particularly useful for removing adhesives and decals, softening adhesives, sealing joints, bending PVC pipes, shrinking tubing, and desoldering components. In the automotive industry, heat guns can be used to remove decals, badges, or tint film from vehicles without leaving residue or damaging paintwork. This technique can also be used to remove adhesives and residue from packaging in the retail industry.
When using a heat gun on plastic, it is important to control the heat carefully. Excessive heat can cause the plastic to warp, melt, or become brittle, while insufficient heat will not produce the desired effect. The key to success is to maintain control over the heat and apply it evenly across the surface. It is also important to wear protective gear, such as heat-resistant gloves, safety goggles, and working in a well-ventilated area to avoid inhaling any fumes.
Before using a heat gun on plastic, it is crucial to prepare the surface and the surrounding area. This includes removing any dirt, grease, or residue, as well as old coatings such as paint. It is also important to protect adjacent areas that may be sensitive to heat, such as glass, metal, or other plastic surfaces. Testing the process on a small, hidden area of the plastic is recommended before proceeding.
While heat guns can be effective for restoring plastic, it is important to note that improper use can lead to melted or damaged plastic. The process requires patience and precision, as rushing can result in uneven results or permanent damage. Additionally, repeated use of this technique can cause the plastic to become brittle over time. Therefore, it is important to consider alternative options, such as cleaning, painting, or using a plastic restorer product.
