Rhino liner can be applied to plastic surfaces, but it may not adhere well and can flake off. To improve adhesion, it is recommended to roughen the plastic surface with sandpaper or steel wool before applying the liner. Additionally, cleaning the plastic with acetone or a similar product can help ensure that the surface is free of any residue that may interfere with the adhesion of the liner. Some people opt to use a special adhesion coating or promoter before applying the liner to further enhance its ability to stick to plastic. While it is possible to apply Rhino liner to plastic, it may require more preparation and care than applying it to other surfaces.

Rhino liner application methods: spray, roll-on, brush
Rhino Linings is a well-known brand that offers protective coatings for vehicles, floors, roofs, truck beds, boats, and more. The company's spray-on protective liners are known for their durability and are designed to safeguard vehicles from weather conditions, scratches, and scrapes.
There are different methods for applying Rhino liner, including spraying, roll-on, and brushing. Spraying is the most commonly discussed application method for Rhino liner. The product can be sprayed onto surfaces like truck beds, bumpers, fenders, and grilles, creating a seamless and impenetrable barrier. Spraying allows for a uniform and thorough coating, ensuring that the liner adheres well to the surface.
Some users have mentioned using a roll-on method for Rhino liner application. While it can be effective, there have been reports of the liner cracking and peeling when the surface is flexed or bent. This method may require more care and preparation of the surface to ensure proper adhesion.
Brushing is another application method mentioned, particularly for smaller areas or detailed work. Brush-on Rhino liner products are available and can provide a durable coating when applied correctly. This method may be more time-consuming but can offer precise control over the application process.
Regardless of the application method, proper surface preparation is crucial for successful Rhino liner adhesion. Cleaning the surface with acetone or a suitable cleaner is essential to remove any dirt, grease, or gloss. Lightly scuffing or sanding the surface can also help create a rough texture, improving the liner's adhesion.
It is important to note that some plastic surfaces may require additional preparation or a special adhesion coating before applying the Rhino liner. Users have reported varying results when applying the liner directly to plastic, with some experiencing flaking or difficulty in achieving proper adhesion. Consulting with a professional Rhino liner applicator or following manufacturer instructions can help ensure optimal results on plastic and other surfaces.

Surface preparation: cleaning, sanding, and scuffing
Before applying a Rhino Liner to plastic, it is essential to prepare the surface by cleaning, sanding, and scuffing it. This process ensures that the liner adheres correctly and creates a durable coating.
Cleaning
The first step is to thoroughly clean the plastic surface to remove any contaminants. This can be done using a cleaner like shampoo or a specific solvent like acetone. It is important to note that acetone can damage some plastics, so it should only be used on surfaces that will be recoated. The cleaning process ensures that the surface is free of any dirt, grease, or gloss that could interfere with the adhesion of the Rhino Liner.
Sanding and Scuffing
After cleaning, the plastic surface needs to be sanded or scuffed to create a rough texture that the Rhino Liner can adhere to. This can be done using sandpaper, steel wool, or a Scotch-Brite scuff pad. It is recommended to use 60 to 100 grit sandpaper for this process. The sanding should be done within masked boundaries, and all edges at the tape lines should be sanded or scuffed to ensure proper adhesion. This step is crucial as it helps create a strong bond between the Rhino Liner and the plastic surface.
It is important to note that the sanding and scuffing process should only be done after the surface has been cleaned to prevent contaminants from being ground into the plastic. Additionally, it is essential to inspect the tools used for this process, such as sandpaper or a cup brush, to ensure they are not overly worn and will effectively scuff the surface.
Once the sanding and scuffing are complete, it is recommended to vacuum or blow away any dust or grit from the surface using compressed air. After that, a final solvent wipe with acetone can be done to ensure the surface is completely clean before applying the Rhino Liner.

Adhesion promoters: improving liner adhesion
Adhesion promoters are used to improve the bonding of plastics, composites, and metals. They are commonly used in industries requiring strong bonds, such as aerospace, automotive, defence, and pharmaceuticals. In the context of improving liner adhesion, adhesion promoters can enhance the bonding of coatings, sealants, and adhesives to plastic surfaces.
There are several types of adhesion promoters, with the most common being silanes and titanates. Silanes are used to bond organic materials to inorganic surfaces, while titanates are used for inorganic material bonding. Adhesion promoters are available in various forms, such as primers, sprays, wipes, and liquids.
When applying a liner to plastic, adhesion promoters can be used to improve the bond strength and durability. This is especially important when bonding dissimilar surfaces, such as plastic to metal, or even metal to metal. In the case of Rhino Liners, adhesion promoters can be applied to plastic surfaces before the liner to enhance adhesion and ensure a long-lasting bond.
To further improve adhesion, surface preparation is crucial. This includes cleaning the plastic surface with acetone or a suitable solvent and creating a rough surface using sandpaper or steel wool. This process increases the surface area and provides a better mechanical grip for the liner, resulting in improved adhesion.
Additionally, adhesion promoters can provide cost savings by reducing the amount of adhesive material needed. They also enable the use of thinner or lighter materials, contributing to weight reduction in automotive and aerospace applications without compromising bond strength.

Weight considerations: added weight from liner coating
When considering adding a liner coating to your vehicle, the additional weight is an important factor to keep in mind. Liners, such as Rhino Liner and Line-X, can add a significant amount of weight to your vehicle, which can impact its fuel efficiency and overall performance.
Rhino Linings is a well-known brand in the liner industry, recognised for its durability and quality. The weight added by a Rhino Liner coating depends on the thickness of the application and the size of the vehicle. For example, a 6-foot truck bed with a 1/2-inch thick Rhino Liner coating can add about 30 to 50 pounds of weight. This thickness is commonly used for truck beds, providing exceptional protection against dinks, dents, and scratches.
Similarly, Line-X is another reputable liner option. It is sprayed to a thickness of 1/8 of an inch and weighs around 0.7 pounds per square foot. For a typical truck bed, the added weight can range from 40 to 70 pounds. While this may not seem like a substantial increase, it is essential to consider the overall weight of the vehicle and the potential impact on fuel consumption.
The weight added by liner coatings can also vary depending on the type of vehicle and the specific application. For instance, coating the entire interior of a Rhino, including both sides, can significantly increase the weight, making it challenging to line up all the holes for the bed and dash. On the other hand, coating only the plastic trim, such as the bumper and step covers, will have a lesser impact on the overall weight.
It is worth noting that while liners add weight to your vehicle, they also provide exceptional protection. Liners are designed to safeguard your vehicle from scratches, dents, and sun bleaching. They offer a durable and attractive solution to keep your vehicle in pristine condition. Additionally, liners can be sprayed on in various colours to complement your vehicle's aesthetic appeal.
