How To Paint Side Mirror Caps

Painting side mirror caps can dramatically enhance a vehicle's aesthetics, offering a personalized touch or restoring faded color. This process, while relatively straightforward, requires careful preparation and execution to achieve a professional-looking finish. This article outlines the steps involved in painting side mirror caps, ensuring a durable and visually appealing result.

Removing the Side Mirror Caps

The first step is removing the mirror caps from the vehicle. This process varies depending on the make and model of the car. Some caps are simply clipped onto the mirror housing, while others may be secured with screws or bolts. Consulting the vehicle's owner's manual is highly recommended to understand the specific removal procedure for the particular model.

Consult the owner's manual for specific instructions.
Utilize appropriate tools, such as a trim removal tool or screwdriver.
Exercise caution to avoid damaging the caps or the surrounding areas.

Cleaning and Preparing the Surface

Once removed, the caps must be thoroughly cleaned to ensure proper paint adhesion. Any dirt, grease, or wax residue can interfere with the paint's ability to bond to the surface.

Wash the caps with automotive soap and water.
Use a degreaser to remove any remaining grease or wax.
Dry the caps completely with a clean microfiber cloth.

Sanding the Caps (If Necessary)

If the existing finish is rough or has imperfections, sanding can create a smooth base for the new paint. This step is especially important if the caps are being repainted rather than painted for the first time.

Start with a coarser grit sandpaper (e.g., 320-grit) to remove imperfections.
Gradually move to finer grits (e.g., 400-grit, then 600-grit) to achieve a smooth surface.
Wipe away sanding dust with a tack cloth.

Applying Primer

Primer provides an ideal surface for the paint to adhere to, promoting better color coverage and durability. It also helps to seal the surface and prevent the old finish from bleeding through.

Apply thin, even coats of automotive primer.
Allow each coat to dry completely before applying the next.
Sand lightly between primer coats with fine-grit sandpaper (e.g., 600-grit).
Wipe away sanding dust with a tack cloth.

Applying the Paint

The choice of paint depends on personal preference and the desired finish. Automotive spray paint is the most common option, providing a smooth and even application.

Shake the paint can thoroughly before use.
Apply thin, even coats of paint, holding the can approximately 10-12 inches away from the surface.
Avoid heavy coats, which can lead to drips and runs.
Allow each coat to dry completely before applying the next.
Typically, 3-4 coats of paint are sufficient for adequate coverage.

Applying Clear Coat (Optional)

A clear coat provides an additional layer of protection for the paint, enhancing its gloss and durability. While optional, it is highly recommended, particularly for areas exposed to the elements.

Apply 2-3 thin, even coats of clear coat, allowing each coat to dry completely.
Avoid heavy coats, which can lead to drips and runs.

Wet Sanding and Buffing (Optional)

For an exceptionally smooth and glossy finish, wet sanding and buffing can be performed after the clear coat has cured. This process removes any imperfections, such as orange peel or dust nibs, and enhances the shine.

Use very fine-grit sandpaper (e.g., 2000-grit) and water to lightly sand the surface.
Use a polishing compound and a buffer to restore the gloss.

Reinstalling the Side Mirror Caps

Once the paint and clear coat have fully cured, the mirror caps can be reinstalled. Refer to the vehicle’s owner's manual for the correct reinstallation procedure.

Carefully align the caps and secure them into place.
Ensure all clips or fasteners are properly engaged.

Final Inspection

After reinstallation, inspect the mirror caps for any imperfections or areas that need touch-up. This final check ensures a professional and polished result.
