Step 3: Remove Existing Rust and Damaged Metal

Use a wire brush or grinder with a wire wheel to remove loose rust, paint, and debris from the existing rocker panel. If the rust has eaten through the metal, you may need to use a hammer and chisel to remove the damaged sections. An angle grinder with a cut-off wheel can be used to remove severely damaged areas.

Carefully assess the extent of the damage. If the rust is extensive, you might need to trim away more of the original panel to ensure a clean surface for the new panel to adhere to. Be cautious not to cut into any structural components that aren’t meant to be removed.

Step 4: Test Fit the Slip-on Rocker Panel

Before doing any welding or bonding, test fit the slip-on rocker panel. Slide the panel over the existing rocker panel and ensure it fits properly. Make any necessary adjustments by trimming or bending the new panel to fit snugly. Check the alignment with the doors and other body panels to ensure a flush fit.

Pay close attention to the bottom edge of the panel. It should align with the original design of the rocker panel. If it doesn’t, you may need to trim or bend the new panel to achieve the correct fit.

Step 5: Prepare the Surfaces

Once you’re satisfied with the fit, prepare the surfaces for welding or bonding. Use a wire brush or grinder to remove any remaining rust or paint from the areas where the new panel will attach. Clean the surfaces thoroughly with a degreaser to remove any oil, grease, or dirt.

If you’re welding, it’s essential to remove all paint and rust to ensure a good weld. If you’re using metal bonding adhesive, follow the manufacturer’s instructions for surface preparation. This usually involves cleaning and roughening the surfaces to improve adhesion.

Step 6: Apply Rust Converter (optional but Recommended)

Apply rust converter to any remaining rust on the original rocker panel. This will help prevent future corrosion. Follow the manufacturer’s instructions for application and drying time.

Step 7: Attach the Slip-on Rocker Panel

There are two primary methods for attaching slip-on rocker panels: welding and metal bonding. The best method depends on your skills and the tools you have available. (See Also: Will Two Brothers Slip On Exhaust Work For Rebel 300 )

Welding Method

Position the Panel: Carefully position the slip-on rocker panel over the existing rocker panel. Use clamps to hold the panel in place. Ensure that it’s aligned correctly with the doors and other body panels.
Weld the Panel: Using a MIG welder, weld the new panel to the existing rocker panel. Start by tack welding the panel in several places to hold it in position. Then, weld along the seams, creating a continuous weld.
Grind the Welds: Once the welds have cooled, use an angle grinder with a grinding wheel to smooth the welds. Grind them flush with the surrounding metal.
Inspect the Welds: Inspect the welds for any gaps or imperfections. If you find any, re-weld those areas.

Metal Bonding Method

Position the Panel: Carefully position the slip-on rocker panel over the existing rocker panel. Use clamps to hold the panel in place. Ensure that it’s aligned correctly with the doors and other body panels.
Apply the Adhesive: Apply the metal bonding adhesive according to the manufacturer’s instructions. This usually involves mixing the adhesive and applying it to the surfaces where the panel will attach.

Remove Clamps: Once the adhesive has fully cured, remove the clamps.

Step 8: Fill and Smooth Imperfections (optional)

If there are any gaps or imperfections, use body filler (Bondo) to smooth them out. Apply the body filler to the affected areas, and then sand it smooth with sandpaper. This will ensure a seamless finish.

Use progressively finer grits of sandpaper to achieve a smooth surface. Start with a coarser grit and gradually move to a finer grit. Be patient and take your time to get the surface as smooth as possible.

Step 9: Prime and Paint

Once the body filler is dry and sanded, prime the entire area with a rust-inhibiting primer. This will protect the metal from future corrosion and provide a base for the paint. Let the primer dry completely according to the manufacturer’s instructions.

After the primer has dried, apply several coats of paint to match the color of your vehicle. Allow each coat to dry before applying the next. Follow the manufacturer’s instructions for drying times.

Step 10: Finishing Touches

After the paint has dried, you can apply a clear coat for added protection and shine. Once the clear coat is dry, you can wet sand and buff the area to blend the new paint with the existing paint. This will ensure a seamless finish.

Remove any masking tape and clean up the work area. Inspect your work to ensure everything is aligned properly and that the finish is smooth and even.

Step 11: Reassemble and Inspect

Lower the vehicle and remove the jack stands. Reinstall any components that you removed for access. Inspect your work to ensure everything is secure and that the new rocker panel is properly aligned. Take your car for a test drive to check for any issues.
