Types of Glue for Auto Body Repair
When it comes to auto body repair, there are several types of glue that can be used to bond body panels. Choosing the right glue is crucial to ensure that the bond is strong and durable. Here are some types of glue that are commonly used in auto body repair:
- Two-part epoxy: This type of glue is known for its strength and durability. It can be used to bond various materials, including metal, plastic, and fiberglass. One of the advantages of using two-part epoxy is that it can be sanded once it dries, making it ideal for auto body repair. However, it can take several hours to cure completely, which may not be ideal for those who need a quick fix.
- Single-part epoxy: This type of glue is similar to two-part epoxy, except that it only requires one component to be applied. Single-part epoxy is often used for filling gaps or cracks in body panels, as it can be easily sanded once it dries. However, it may not be as strong as two-part epoxy and may take longer to dry.
- Super glue: Also known as cyanoacrylate glue, super glue is a fast-drying adhesive that can bond plastic, metal, and other materials. It can be useful for small repairs, but it may not be strong enough for larger patches or panels. Additionally, it can be difficult to remove once it dries, so it’s important to use it sparingly.
- PL glue: This type of glue is designed specifically for bonding plastics. It can be useful for auto body repair, as many car parts are made of plastic. PL glue also has a relatively fast curing time, which can be beneficial for those who need a quick repair. However, it may not be as strong as other types of glue and may require the use of a primer.
It’s important to choose the right type of glue for the specific repair that you’re performing. If you’re not sure which glue to use, consult a professional or do some research to find the best option for your needs. Additionally, be sure to consider factors such as curing time, strength, and ease of use when selecting a glue.
Preparation
Before starting the process of gluing body repair panels, it is crucial to prepare the surface properly. Preparing the surface ensures a strong bond and a seamless repair. Any dirt, rust, or paint residue should be removed, and the surface should be sanded to create a rough texture that the glue can adhere to. In this way, the glue can penetrate the surface well and provide a strong bond. Let’s discuss some necessary steps for preparation below.
Clean and Sand the Surface
Before gluing body repair panels, it is important to properly clean and sand the surface. This step is crucial to ensure the best possible bond between the panels and the glue. Here are the steps to follow:
| Step 1: | Clean the surface using a scraper, a wire brush, and a cleaning solvent. This will remove any grease, dirt, rust, or old paint that could interfere with the bonding process. |
| Step 2: | Sand the surface using 80-grit sandpaper. This will create a rough texture and increase the surface area for better bonding. |
| Step 3: | Use a wax and grease remover to clean the surface one more time. This will get rid of any dust or residue from sanding. |
| Step 4: | Let the surface dry completely before applying the glue. |
It is worth noting that some glues, such as E6000 glue, require a slightly different cleaning process. You can learn more about E6000 glue and how to use it by checking out our article on What is E6000 glue?.
Additionally, when sanding the surface, it is important to wear a mask and safety goggles to prevent inhaling dust and debris. You can learn more about safety precautions when working with glue in our section on safety precautions.
Protect Non-Bonding Areas
When it comes to gluing body repair panels, it’s important to protect non-bonding areas from unintentional glue residue. This can be achieved by covering the areas with masking tape or plastic sheeting. It’s important to make sure the tape or plastic is firmly attached to prevent any glue from seeping through.
Using masking tape is a common practice in auto body repair. You should apply the tape around the edges of the area you’re bonding to ensure that the glue does not spill over onto any other part of your vehicle. It’s important to use strong tape that will not easily peel or break during the gluing process.
Plastic sheeting can also be used to protect non-bonding areas. It provides an additional layer of protection from glue drips that can adhere to your vehicle and other nearby surfaces. To prevent movement of the plastic sheet, you can use strong magnets to hold it in place.
Pro tip: Before gluing, use a rag and rubbing alcohol to clean the non-bonding areas of any dirt or oil. This will help the masking tape or plastic adhere better.
By taking the time to properly protect non-bonding areas, you can avoid any unwanted mess and have a cleaner finish. Now that we’ve covered this important step, let’s move on to the gluing process.

To test fit the panels, follow these steps:
- Carefully place the panels over the damaged area and position them precisely how they should fit once glued.
- Check for any gaps or misalignments. If you notice any, gently remove the panels and adjust them accordingly until they fit perfectly.
- Confirm that there is enough space and clearance for any wires, hoses, or other parts.
- Once you’re satisfied with the fit, mark the position of the panels using masking tape to help keep everything in place during the gluing process.
Testing the panels before applying glue is important because it helps you avoid any potential issues during the gluing process. Any misalignments or gaps in the panels can cause the glue to seep out, affecting the quality of the bond. It’s also essential to make sure that any wires or hoses are not obstructed or pinched when the panels are in place.
If you encounter any fit issues, take the time to adjust the panels until the fit is perfect. This can be done by carefully bending small areas of the panel to ensure they align perfectly, or by using a rubber mallet to tap any edges that aren’t lining up correctly.
Testing the fit of the panels is a crucial step in the gluing process. By taking the time to ensure that the panels fit perfectly, you can avoid any potential issues, and create a reliable and secure bond. Now that you’ve successfully test-fitted your panels, it’s time to move onto the next step in the process and begin gluing the panels using an appropriate glue, such as PL glue.
Gluing Process
Once you have properly prepared your auto body repair panels, it is time to move on to the gluing process.

- If using a two-part adhesive, mix the two components according to the instructions provided by the manufacturer.
- Apply the mixed adhesive to the bonding surface using an applicator or disposable brush, taking care to spread it evenly across the surface.
- Note: Be sure to work quickly with two-part adhesives as they can dry fast!
It’s important to apply the glue evenly to ensure a strong bond. Applying too much glue can create an uneven bond and excessive gaps between the panels which may cause future problems. On the other hand, insufficiently applying the glue may weaken the bond and leave gaps that can cause significant durability issues.
Remember that the correct amount of glue to use is crucial, and you should consider the size and depth of the repair area. In any case, you can always note this in the “Tips and Tricks” section of our guide.
Now that the glue has been applied, it’s time to clamp the panels together. Continue reading to learn about this critical step!
Clamp the Panels
Clamping the Panels is the next crucial step after applying the glue. The clamps will hold the panels together until the glue dries completely. Without proper clamping, the body repairs may not set correctly and may shift, leading to misaligned body parts.
To clamp the panels correctly, follow these steps:
- Choose the appropriate clamps: Based on the size and shape of the panel, and the location where the repair is needed, select the clamps that fit best. For larger repairs, C-clamps can be used, and for smaller repairs, mini clamps can be used.
- Place the clamps perpendicular to the glued area: Place the clamps perpendicular to the glued area and adjust them so that they are tight enough to hold the panels together but not too tight that it will squeeze the glue out of the joint.
- Check for alignment: Before applying all the clamps, ensure that the panels are correctly aligned. To maintain perfect alignment, use a straight edge or a laser pointer.
- Add more clamps if needed: For larger repairs, additional clamps may be added if necessary. Ensure that the clamps are placed evenly on both sides of the glued area, and that they are not putting excessive force on one side.
Keep in mind that the clamps should be left in place for the recommended time to allow the glue to dry completely. This time may vary depending on the type of glue used and the environmental conditions. Be sure to refer to the manufacturer’s instructions for the recommended drying time.
Clamping the panels is critical in ensuring that the repair holds up correctly. With the correct clamping technique, the repaired area should look and feel like new. By following these steps, you will ensure that the body repair panels will stay in place for years to come.

Fill the Gaps
After clamping the panels together, it’s important to fill any gaps between them. This will ensure that the bond is strong and the panels will not come apart later on. Before filling the gaps, make sure that the glue has dried completely. If you try to fill the gaps before the glue has dried, it may not hold properly.
To fill the gaps, you will need to use a body filler. This is a two-part compound that consists of a resin and a hardener. When the two parts are mixed together, they harden to form a strong and durable material that can be sanded and shaped.
Step 1: Mix the body filler according to the instructions on the package. You will typically need to mix equal parts of the resin and the hardener.
Step 2: Apply the body filler to the gap using a plastic spreader. Make sure that the gap is completely filled with the filler.
Step 3: Wait for the filler to dry completely. This can take anywhere from a few hours to overnight, depending on the temperature and humidity.
Step 4: Sand the filler down using a sanding block or sandpaper. Start with a coarse grit sandpaper and work your way up to a finer grit. This will help to smooth out any bumps or rough spots.
Once you have sanded the filler down, the repair should be virtually undetectable. If you need to paint the repaired area, make sure to prime it first before applying any paint.
It’s worth noting that there are other materials that you can use to fill gaps in auto body repair, such as plastic welding or seam sealer. However, body filler is the most commonly used material and is a great choice for most repairs.
Tips:
- Make sure to wear gloves when working with body filler, as it can be difficult to wash off.
- Be sure to work in a well-ventilated area to avoid breathing in fumes from the body filler.
- Only mix as much body filler as you need for the repair, as it hardens quickly and cannot be reused once it has set.
Filling gaps in auto body repair is an essential step in ensuring a strong and durable bond between panels. By following the steps outlined above and using body filler, you can achieve a seamless repair that will last for years to come.
Finishing Touches
Once you have glued the body repair panels together, there are still some finishing touches that need to be done to make the repair job look seamless. Here are some steps to follow for finishing touches:
1. Sand Down Excess Glue: Once the glue has dried, use sandpaper to sand down any excess glue. Start with rough grit and then move to finer grit to ensure that the surface is smooth.
2. Prime the Surface: Apply a layer of primer on the repaired area to ensure that the paint will adhere properly. This will also help protect the metal from rusting.
3. Paint: Apply a layer of paint that matches the color of the car. Paint in small strokes in the same direction as the rest of the car’s paint to ensure that it blends well.
4. Buff and Shine: Once the paint has dried, use a buffer to blend the painted area with the rest of the car’s paint. Then, shine the area with a polishing compound to give it a glossy finish.
Remember, the finishing touches are just as important as the gluing process. Taking the time to do them correctly will make the repair job look professional and seamless.
As a general note, it’s important to use the correct type of glue for auto body repair. Using the wrong type of glue could lead to an unstable repair job.
