Quarter Panel Mould

What You’ll Need
First things first, let’s talk about the tools and materials you’ll need for the installation. You don’t need a whole bunch of fancy stuff, but having the right things on hand will make the process a whole lot easier.
- Quarter Panel Mould: Obviously, you’ll need the mould itself. Make sure you’ve got the right size and style for your vehicle.
- Adhesive: A good quality automotive adhesive is essential for a secure fit. I recommend using a product that’s specifically designed for this type of installation.
- Cleaning Supplies: You’ll need to clean the surface where the mould will be installed. Use a degreaser and a microfiber cloth to remove any dirt, grease, or wax.
- Measuring Tools: A tape measure and a level will help you ensure that the mould is installed straight and in the right position.
- Utility Knife: You might need to trim the mould to fit your vehicle, so a sharp utility knife is a must.
- Masking Tape: This will help you mark the position of the mould before you apply the adhesive.
Preparing the Surface
Before you start installing the quarter panel mould, you need to prepare the surface where it will be attached. This is an important step because it will ensure that the adhesive bonds properly and the mould stays in place.
- Clean the Surface: Use a degreaser to clean the area where the mould will be installed. Make sure you remove all dirt, grease, and wax. You can use a microfiber cloth to wipe the surface clean.
- Sand the Surface: If the surface is smooth, you might need to sand it slightly to create a rough surface for the adhesive to bond to. Use a fine-grit sandpaper and sand the area in a circular motion.
- Wipe the Surface Again: After sanding, wipe the surface again with a clean microfiber cloth to remove any dust.
Measuring and Marking
Once the surface is clean and prepared, it’s time to measure and mark the position of the quarter panel mould. This will ensure that the mould is installed straight and in the right place.
- Measure the Mould: Use a tape measure to measure the length and width of the mould. Make sure you measure from the edges of the mould, not the center.
- Mark the Position: Use masking tape to mark the position of the mould on the vehicle. Make sure the tape is straight and in the right place. You can use a level to ensure that the tape is level.
- Check the Fit: Before you apply the adhesive, check the fit of the mould. Make sure it fits properly and that there are no gaps between the mould and the vehicle.
Applying the Adhesive
Now that you’ve measured and marked the position of the mould, it’s time to apply the adhesive. This is a critical step, so make sure you follow the instructions on the adhesive carefully.
- Apply the Adhesive: Apply a thin layer of adhesive to the back of the mould. Make sure you cover the entire surface of the mould.
- Press the Mould into Place: Carefully press the mould into place on the vehicle, following the markings you made with the masking tape. Make sure the mould is straight and in the right position.
- Hold the Mould in Place: Hold the mould in place for a few minutes to allow the adhesive to bond. You can use a clamp or a piece of tape to hold the mould in place if necessary.
- Remove the Masking Tape: Once the adhesive has bonded, remove the masking tape.
Trimming the Mould
After the mould is installed, you might need to trim it to fit your vehicle. This is a simple process, but it’s important to be careful not to damage the mould.
- Use a Utility Knife: Use a sharp utility knife to trim the edges of the mould. Make sure you cut along the edge of the mould, not into the vehicle.
- Sand the Edges: After trimming, sand the edges of the mould to smooth them out. Use a fine-grit sandpaper and sand the edges in a circular motion.
Finishing Touches
Once the mould is installed and trimmed, it’s time to add the finishing touches. This will make the mould look professional and give your vehicle a clean, polished look.
- Clean the Mould: Use a clean microfiber cloth to clean the mould. Make sure you remove any dirt or debris.
- Apply a Protective Coating: You can apply a protective coating to the mould to help prevent it from fading or scratching. There are many different types of protective coatings available, so choose one that’s suitable for your vehicle.
- Check the Fit: Once the protective coating has dried, check the fit of the mould again. Make sure it’s still straight and in the right position.
Conclusion
Installing a quarter panel mould isn’t rocket science, but it does require a little bit of patience and attention to detail. By following these steps, you should be able to install the mould yourself and give your vehicle a new look.
