Any other trim pieces: Carefully remove any other trim that might be in the way.

Store these components in a safe place where they won’t be damaged. Take pictures before removing parts to help you remember where everything goes during reassembly.

Step 4: Cleaning and Rust Removal

This is the most critical step in the preparation process. Thoroughly clean the existing rocker panel and surrounding areas. Use a wire brush, grinder with a wire wheel, or a sandblaster to remove all rust, loose paint, and debris. Pay close attention to the areas where the new panel will overlap the old one.

Wire Brush: For light rust removal.
Grinder with Wire Wheel: For more aggressive rust removal.
Sandblasting: If you have access to a sandblaster, this is the most effective method, but requires more equipment and expertise.

Once you’ve removed the loose rust, use a rust converter to treat any remaining rust. This will help to prevent future corrosion. Follow the manufacturer’s instructions for the rust converter, which typically involves applying it to the rusted surface and allowing it to dry.

Step 5: Preparing the Surface

After rust removal, use sandpaper to smooth out the surface and create a good base for the new panel. Start with a coarser grit sandpaper (e.g., 80-grit) to remove any remaining imperfections, then move to a finer grit (e.g., 180-grit) for a smoother finish. Clean the surface thoroughly with wax and grease remover to remove any residue.

Installing the Slip-on Rocker Panels

With the preparation complete, you can now install the slip-on rocker panels. This process involves fitting the panels, securing them, and sealing the seams.

Step 1: Test Fitting the Panel

Before permanently attaching the panel, test-fit it to ensure it fits properly. Slide the panel over the existing rocker panel, making sure it aligns correctly with the body lines and door openings. Check for any obstructions or areas where the panel might not fit flush. You might need to gently bend or adjust the panel to achieve a good fit. If any modifications are needed, make them now, before you start securing the panel.

Step 2: Positioning and Clamping

Once you are satisfied with the fit, position the panel in its final location. Use clamps, tape, or other methods to hold the panel securely in place while you work. Ensure the panel is flush with the surrounding body panels and that there are no gaps. Double-check the alignment before proceeding to the next step.

Step 3: Securing the Panel

There are two primary methods for securing the slip-on rocker panel: rivets or self-tapping screws. Choose the method that best suits your needs and skill level.

Using Rivets

Rivets provide a strong and durable connection. Follow these steps:

Drill Holes: Using the holes in the new rocker panel as a guide, drill holes through both the new panel and the existing rocker panel. Drill holes approximately every 6-8 inches along the top and bottom edges of the panel.
Insert Rivets: Insert the rivets into the holes.
Use a Riveter: Use a rivet gun to set the rivets, ensuring they are flush with the panel.

Using Self-Tapping Screws

Self-tapping screws are easier to install than rivets. Follow these steps: (See Also: Will Two Brothers Slip On Exhaust Work For Rebel 300 )

Drill Pilot Holes: Drill pilot holes through the new rocker panel and into the existing rocker panel. The size of the pilot hole should be slightly smaller than the diameter of the self-tapping screw.
Install Screws: Use a screwdriver or drill to install the self-tapping screws, securing the panel to the existing rocker panel. Space the screws approximately every 6-8 inches along the top and bottom edges of the panel.

Regardless of the method you choose, make sure the fasteners are evenly spaced and provide a secure attachment. Do not overtighten the screws, as this could damage the panel.

Step 4: Sealing the Seams

Sealing the seams is crucial to prevent moisture from getting between the new and old panels, which could lead to rust. Use seam sealer to seal the gaps along the top and bottom edges of the new panel.

Apply Seam Sealer: Use a caulk gun to apply a bead of seam sealer along the top and bottom edges of the panel, where it meets the body of the truck.
Smooth the Sealer: Use a putty knife or your finger (wearing gloves) to smooth the seam sealer, creating a clean, watertight seal.
Allow to Dry: Allow the seam sealer to dry completely according to the manufacturer’s instructions.

Painting the Slip-on Rocker Panels

Painting the slip-on rocker panels will protect them from corrosion and ensure they match the color of your Silverado. This step requires careful preparation and application.

Step 1: Surface Preparation

Before painting, thoroughly clean the surface of the rocker panel with wax and grease remover. This will remove any dirt, oil, or contaminants that could interfere with the paint adhesion. Lightly sand the panel with fine-grit sandpaper (e.g., 320-grit) to create a slightly rough surface for the paint to adhere to.

Step 2: Masking

Use masking tape and paper to protect the surrounding areas of your Silverado, such as the doors, fenders, and any other parts that you don’t want to paint. Ensure the masking tape is securely applied to prevent paint from bleeding onto unwanted areas.

Step 3: Priming

Apply a thin, even coat of primer to the rocker panel. Primer provides a base for the paint and helps it adhere to the metal surface. Follow the manufacturer’s instructions for the primer, including the recommended drying time. Allow the primer to dry completely before proceeding to the next step.

Step 4: Painting

Apply several thin coats of paint to the rocker panel, allowing each coat to dry before applying the next. This will help to prevent runs and drips, and ensure a smooth, even finish. The number of coats required will depend on the paint you are using, but typically 2-3 coats are sufficient. Use the correct paint code for your Silverado. Consult your owner’s manual or a paint supplier to determine the correct paint code.

Step 5: Clear Coating (optional)

If desired, apply a clear coat to the painted surface. Clear coat adds an extra layer of protection and provides a glossy finish. Apply several thin coats of clear coat, allowing each coat to dry before applying the next. Again, follow the manufacturer’s instructions for the drying time.

Step 6: Final Inspection

Once the paint and clear coat (if applied) are completely dry, carefully remove the masking tape. Inspect the painted surface for any imperfections, such as runs, drips, or uneven areas. If necessary, you can lightly sand any imperfections with fine-grit sandpaper and touch up the paint. Allow the paint to fully cure before washing or waxing the area.

Reassembling and Finishing Touches

After the paint has dried, it’s time to reassemble any trim, moldings, or other components that you removed earlier. This includes door seals, mud flaps, running boards, and any other trim pieces. Carefully reattach all the components, ensuring they are properly aligned and secured. (See Also: Will You Lose Low End With M4 Slip On Fz07 )
