Removing the sleeper for painting
Removing the sleeper of a heavy truck for painting is a complex process that requires careful planning and execution. Here is a step-by-step guide to help you through the process:
Preparation
Before beginning the removal process, it is essential to have a clear workspace and gather the necessary tools and materials. Ensure you have a paint gun, an air compressor with a water trap, paint strainers, masking tape, sandpaper, and other standard painting supplies. Additionally, you may require some friends or helpers to assist with lifting and moving heavy components.
Engine and Component Removal
For easier access and a higher-quality paint job, consider removing the engine, hood, fuel tanks, airbags, and brake components. Remove any chrome or aluminium parts, as well as the exhaust tubing and muffler. The more components you can separate and coat individually, the better the final paint job will be.
Disconnecting the Sleeper
To remove the sleeper from the truck, start by disconnecting any relevant wiring and hoses. Remove body mounting points, bags, and shocks. Air lines can be easily detached from their fittings or cut and replaced during reassembly. Ensure you have adequate support and a stable surface to lift and move the sleeper once it is detached.
Surface Preparation
After removing the sleeper, prepare the surface for painting by sanding it down using sandpaper or a palm sander. This step ensures the paint will adhere properly to the surface. If necessary, apply primer to areas that require more attention or body filler. Mask off any areas you do not want to be painted, such as windows or other components.
Painting
Once the sleeper is prepared and masked off, it's time to paint. Mix your chosen paint with a hardener to ensure faster drying, and pour it into your paint gun. Test spray on a panel to ensure the gun is functioning correctly. Start by painting door jambs, allowing them to dry, and then apply as many coats as needed. Follow this by applying a base coat to the entire sleeper, allowing it to tack up before laying down a heavier coat to ensure complete coverage.
Remember to follow safety precautions, including wearing protective gear and working in a well-ventilated area, during the removal and painting process.

Filling in the holes with rivets
Filling in holes with rivets is a common technique used in heavy-duty truck repairs. Here is a step-by-step guide on how to fill in holes with rivets:
Preparation
Before starting the filling process, it is important to have the right tools and materials. Gather the necessary tools, such as a drill, clamps, a dual-action sander, and a filler spreader or acid brush. Ensure you have the appropriate rivets, such as closed-end rivets or sealed head rivets, and an approved low-VOC surface cleaner and wax and grease remover.
Cleaning and Sanding
Begin by clamping the panels together. Clean the truck body and the service part with the approved low-VOC surface cleaner to remove any dirt or grease. Next, use the dual-action sander with a 3M 80-grade abrasive to sand the mating flanges on both the truck and the service part. This process helps create a smooth surface for the rivets to adhere properly.
Applying Adhesive
After sanding, re-clean the surfaces with an approved low-VOC wax and grease remover to ensure they are free of any residue. Apply a thin bead of adhesive to the mating flange(s) using the filler spreader or acid brush. Cover the bare metal area completely and spread the adhesive to achieve a thin, uniform layer. Allow the adhesive to cure according to the manufacturer's instructions.
Drilling and Deburring
If your rivets require drilling, clamp the panels together and drill the holes. It is important to deburr the drilled holes to remove any burrs that may prevent the panels from fitting properly. You can use a drill bit or a burr inside the hole to achieve this. Clean the holes with the approved low-VOC cleaner to ensure they are free of any debris.
Priming and Corrosion Protection
Apply a thin coat of primer and, if possible, alodine to the inside edge of the holes to slow down corrosion. This step will help protect the rivets and surrounding areas from rust and deterioration.
Inserting Rivets
Before inserting the rivets, apply a thin coat of adhesive to the edges of the drilled holes to cover any exposed metal. Then, insert the rivets into the holes. Ensure you are using the proper rivet recommended by the OEM (Original Equipment Manufacturer).
Finishing
Once the rivets are in place, you can finish the process by sanding the rivets and filling them with body putty or Bondo to create a smooth appearance. You can also use paintable calking if it is a minor DIY project. Allow the putty or filler to dry, and then sand it down to match the surrounding surface.
By following these steps, you can effectively fill in the holes with rivets, creating a strong and durable bond that will enhance the appearance and functionality of your heavy truck.

Removing the sleeper to convert to a flatbed
Converting a truck to a flatbed can be a great option for carrying heavy and unusually shaped loads. The process can vary in difficulty depending on factors such as the size, shape, and materials used for the existing bed. Here are the steps to remove the sleeper and convert it into a flatbed:
Step 1: Remove the Tail Lights
First, remove the tail lights from the truck. This will give you access to the bolts securing the bed to the truck.
Step 2: Remove the Bolts
There are typically six bolts holding the truck bed in place. Two bolts are usually located near the cab, and four are towards the rear of the frame. Use a wrench to remove the bolts. If they are rusted or difficult to remove, you may need to use a cutting torch or a reciprocating saw to cut through them.
Step 3: Cut and Weld Metal Pieces
Cut steel sheets and tubing to the appropriate size. Use clamps to hold these pieces in place while cutting. Weld the metal pieces onto the bed frame, creating a sturdy base for the flatbed. Clean the welded areas properly to ensure a smooth finish.
Step 4: Prepare the Wooden Boards
If the existing wooden boards are in good condition, you can choose to reuse them. Otherwise, cut new wooden boards to the required size. Paint or treat the wooden boards to protect them from weather damage and rust. This step will ensure the longevity of your flatbed.
Step 5: Mount the Lumber and Reinstall Tail Lights
Mount the wooden boards securely behind the vehicle. Reinstall the tail lights, or if you prefer, install new trailer lights by wiring them into the existing trailer light wiring harness.
Converting a heavy truck into a flatbed requires careful planning and execution. It is important to consider the size and type of flatbed that best suits your needs, as well as any additional features such as a liftgate or a gooseneck hitch for towing. Remember to always prioritize safety and follow the specific instructions and guidelines for your vehicle.
