Types Of Body Side Moldings
Body side moldings come in different materials. Each type offers unique benefits and fits various car styles. Choosing the right molding depends on durability, look, and cost.
Plastic Moldings
Plastic moldings are lightweight and flexible. They resist dents and scratches well. These moldings often have a smooth finish. They are easy to install and replace. Plastic moldings suit many car models. They provide good protection without adding weight.
Metal Moldings
Metal moldings are strong and long-lasting. They add a classic, polished look to cars. Metals like aluminum or stainless steel are common. These moldings resist corrosion and impact. Metal moldings require careful installation. They usually cost more than plastic ones.
Rubber Moldings
Rubber moldings offer excellent shock absorption. They protect car sides from minor bumps and scratches. Rubber is flexible and weather-resistant. These moldings are often used on trucks and SUVs. They provide a rugged appearance. Rubber moldings are easy to maintain and replace.
Materials Used In Moldings
Body side moldings protect car doors from dents and scratches. The material used affects durability and look. Different materials offer unique benefits and challenges. Understanding these helps in choosing the right molding.
Common Plastics
Plastics are popular in body side moldings. They are lightweight and cost-effective. ABS (Acrylonitrile Butadiene Styrene) is one common plastic used. It offers good impact resistance and easy shaping. Polypropylene is another plastic type, known for flexibility and toughness. Plastics also resist rust and corrosion well.
Metal Alloys
Metal alloys provide strong and durable moldings. Aluminum is widely used for its light weight and rust resistance. Steel alloys offer high strength but need coatings to prevent rust. Metal moldings give a premium look and better impact protection. They can be bent or shaped to fit car contours precisely.
Composite Materials
Composite materials combine plastic and fiber for added strength. Fiberglass is a common composite, offering stiffness and light weight. Carbon fiber composites are strong but expensive, used in high-end cars. These moldings resist dents and maintain shape better than pure plastic. Composites also allow more design flexibility.
Connection Methods
Body side moldings attach to a vehicle in several ways. These connection methods keep the moldings secure and aligned. Each method suits different car designs and materials. Understanding them helps in repairs and replacements.
Adhesive Bonding
Adhesive bonding uses strong glue to attach moldings. The glue sticks the molding directly to the car body. It creates a smooth, clean look without visible hardware. This method is common for plastic or lightweight moldings. Proper surface cleaning is key for strong bonding.
Clips And Fasteners
Clips snap moldings onto the car’s side panels. They hold the molding firmly in place. Fasteners may include small plastic or metal parts. These allow easy removal and replacement of moldings. Clips are popular for flexible or curved moldings.
Screws And Bolts
Screws and bolts provide a very secure connection. They go through the molding into the car frame. This method is strong and long-lasting. Visible screws can be covered with caps for a neat look. It is often used on metal moldings or heavy-duty parts.
Double-sided Tape
Double-sided tape offers a quick and simple way to attach moldings. It sticks on both the molding and the car surface. This tape is thick and weather-resistant. It works best on smooth, clean surfaces. Tape connections are usually less permanent than screws or clips.
Step-by-step Installation Process
Installing body side moldings involves several clear steps. Each step ensures the molding fits well and stays secure. Follow this process carefully to get the best results.
Surface Preparation
Clean the car surface where the molding will go. Use soap and water to remove dirt. Dry the area fully to avoid moisture. Wipe with rubbing alcohol to remove oils. This helps the adhesive stick properly.
Aligning The Molding
Hold the molding next to the car. Check its shape and length against the door or panel. Mark the position with a light pencil line. Make sure it is straight and even. Proper alignment prevents gaps and uneven edges.
Securing The Molding
Peel off the backing from the adhesive tape. Press the molding firmly onto the marked area. Start from one end and move to the other. Apply even pressure to avoid air bubbles. Some moldings may use clips or screws; install them as needed.
Final Inspection
Look closely at the installed molding. Check for loose edges or gaps. Press any weak spots firmly again. Clean any marks or fingerprints from the surface. Ensure the molding is secure and looks smooth.
Tools Required For Installation
Installing body side moldings requires the right tools. Using proper tools makes the job easier and ensures a secure fit. Gather all necessary items before you begin. This preparation saves time and prevents mistakes.
Basic Hand Tools
You need simple hand tools for the job. A screwdriver set helps remove old moldings and tighten new ones. A plastic trim remover protects your car’s paint while prying off old parts. Measuring tape ensures moldings align perfectly. Clean cloths help wipe surfaces before installation.
Specialized Equipment
Some tasks need special tools. A heat gun softens moldings for easier bending and fitting. Double-sided automotive tape applies moldings securely without damage. Panel clip pliers remove clips without breaking them. These tools improve precision and protect your car’s finish.
Safety Gear
Safety is important during installation. Wear gloves to protect your hands from sharp edges. Safety glasses shield your eyes from dust or debris. A dust mask keeps you safe from particles if sanding or cleaning surfaces. Staying safe means a smoother, worry-free installation.

Common Issues And Fixes
Body side moldings protect your car and give it a nice look. Over time, these moldings can face issues. Fixing these problems early keeps your car safe and looking good. Below are common problems and easy fixes to help maintain your moldings.
Loose Moldings
Loose moldings often happen from bumps or poor installation. They can fall off while driving, which is dangerous. To fix this, clean the area well and use strong double-sided tape. Press the molding firmly for a few minutes. In some cases, screws or clips may need tightening or replacing.
Peeling Adhesive
Peeling adhesive happens due to heat, moisture, or old age. This makes the molding start to lift or fall off. Remove the molding carefully and clean off old glue. Apply new automotive adhesive or double-sided tape. Let it dry before driving to ensure a strong bond.
Alignment Problems
Misaligned moldings look bad and may not protect well. This happens if moldings are put on incorrectly or get knocked out of place. To fix alignment, gently remove the molding. Realign it with the car’s body lines. Reattach with tape or clips, making sure it sits evenly and straight.
Maintenance Tips
Body side moldings protect your car’s doors from scratches and dents. Proper care keeps them looking good and lasting longer. Follow simple maintenance steps to avoid damage and keep moldings secure.
Cleaning Moldings
Use mild soap and water to clean moldings. Avoid harsh chemicals that can cause fading. Soft cloths work best to prevent scratches. Clean moldings regularly to remove dirt and grime.
Protecting Against Damage
Park in safe spots to avoid door dings. Avoid hitting moldings with shopping carts or bike handles. Consider applying a clear protective film to shield moldings. Small dents can be repaired quickly if noticed early.
Regular Inspections
Check moldings often for loose parts or cracks. Tighten any loose screws or clips carefully. Replace damaged moldings to maintain protection. Regular checks help catch problems before they worsen.
