Repairing Rusted Jeep Paint Chips: Quick Diy Guide

Jeep owners can use a variety of methods to fix small paint chips with rust. The most common approach is to sand down the affected area, apply a primer, and then repaint the surface. Some owners opt for touch-up paint, which can be purchased from dealerships or online, and is available in spray cans or small tubes with brushes. Others have recommended using nail polish that closely matches the colour of the car, or a clear coat to prevent rust. To prevent future rust buildup, regular waxing is recommended, as it acts as a paint cleaner.

Sand down the area

To fix small paint chips with rust on your Jeep, you'll need to sand down the affected area to create a smooth surface before applying primer and paint. Here's a detailed guide on the sanding process:

Start by removing any rust from the chipped area. You can use a dual-action (D/A) sander with 80-grit sandpaper or a cup brush attached to an angle grinder for this step. This will help you quickly remove the rust and any remaining paint from the chipped area, exposing the bare metal underneath. Be sure to wear the appropriate safety gear, including eye protection and a respirator, when working with power tools and rust, which can contain harmful particles.

Once the rust and paint are removed, switch to a finer grit sandpaper, such as 220-grit. Use this to feather the edges around the repair area. Sanding with a finer grit will help create a smoother transition between the bare metal and the surrounding painted surface. Take your time with this step to ensure the area is evenly sanded and free of any rough spots.

After sanding, it is important to clean the area thoroughly to remove any dust or debris generated during the sanding process. Use a tack cloth or a damp cloth to wipe down the area, ensuring it is completely free of any contaminants. This step is crucial as any remaining dust can affect the adhesion of the primer and paint, leading to an uneven or unsatisfactory finish.

If there are any minor imperfections or pitting in the metal after sanding, you may need to apply a small amount of body filler to create a smooth and even surface. Follow the instructions on your chosen body filler product, as drying times and application methods may vary. Once the filler is dry, sand it lightly with the 220-grit sandpaper to ensure a seamless blend with the surrounding area.

Finally, before moving on to the priming and painting stages, inspect the sanded area under good lighting to ensure it is adequately prepared. Run your hand over the surface to check for any remaining rough spots or imperfections. If necessary, repeat the sanding process with the finer grit sandpaper until you achieve a smooth and consistent finish. Remember, taking the time to properly sand and prepare the area will pay off in the final appearance and durability of the repair.

Apply a rust inhibitor

To fix small paint chips with rust on your Jeep, you'll need to apply a rust inhibitor as part of the repair process. Here's a step-by-step guide for addressing the rust and inhibiting its future growth:

Prepare the Area

Start by preparing the affected area. Cut out the rusted section, ensuring you cut a little beyond the rust to remove all traces of it. You'll need to cut out a patch of metal that matches the shape and size of the area you removed. This new patch will replace the rusted section.

Apply the Rust Inhibitor

This is a crucial step to prevent the further spread of rust. Apply a rust inhibitor or undercoating inside the hole (the area from which you cut out the rust) and on the back of your metal patch. Make sure to follow the instructions on your chosen rust inhibitor product for proper application and drying time.

Attach the Metal Patch

Once the rust inhibitor has dried, you can attach the metal patch. Grind or sand the edges of both the hole and the patch to ensure a smooth surface. Tack weld the patch into place, making sure to straighten it if needed. Then, spot weld around the entire patch, being careful not to focus too long on one area to avoid warping.

Final Touches

After welding, grind down the welds and scuff the area to prepare for painting. Use a filler to smooth out any low spots, and then sand the filler until it is smooth and level. Apply a skim coat of body filler over the area and feather it out for a seamless finish. Sand the filler again until it is smooth.

Prime and Paint

Now, you're ready to prime and paint. Apply a filler primer and block it to ensure a smooth surface. Add more primer if needed. Finally, apply paint—multiple coats might be necessary. Tape off a clean edge or blend the paint with the surrounding area for a seamless finish.

Remember, always work in a well-ventilated area when dealing with paints, primers, and rust inhibitors. Additionally, consider practising your techniques on a scrap piece of metal before working on your Jeep to ensure the best possible outcome.

Prime the area

To fix small paint chips with rust on a Jeep, priming the area is an important step. Here is a detailed guide on how to do it:

Before priming, ensure that you have sanded down the affected area to bare metal. This is crucial because paint does not adhere well to metal without a suitable adhesive, such as a primer. Use a dual-action sander with 80-grit sandpaper or a cup brush on an angle grinder to remove all the rust and paint from the chipped area. Feather the edges around the repair area with 220-grit sandpaper to ensure a smooth transition.

Once the area is sanded down, it's time to apply the primer. Choose a high-quality primer, preferably in a spray can, as it provides better coverage and ease of application. Spray an even coat of primer onto the sanded area, ensuring that you follow the instructions on the primer's packaging for the best results. Allow the primer to dry thoroughly according to the manufacturer's instructions.

After the primer has dried, you may need to sand the area again with 220-grit sandpaper to smooth out any imperfections and ensure the surface is ready for painting. Remove any dust or debris with a tack cloth or a damp cloth before proceeding to the next step.

If you want to ensure the best possible adhesion and protection, consider applying a second coat of primer. This step is optional but can provide added durability to the repair. Again, follow the manufacturer's instructions for drying times and application techniques.

By following these steps, you will effectively prime the area, creating a suitable base for the touch-up paint. Remember to work in a well-ventilated area and wear the necessary protective gear, such as gloves and a respirator, when working with primers and paints.

Use touch-up paint

Touch-up paint is an easy, inexpensive, and quick solution to fix small paint chips on your Jeep. You can buy touch-up paint in the form of pens or bottles, with or without a brush. Touch-up paint pens are available at service centres and dealerships, while bottles can be purchased from automotive stores or online.

Before applying touch-up paint, it is important to prepare the chipped area. Clean the surface with denatured alcohol to remove dirt and grime, helping the paint to adhere better. If there is rust present, sand down the area until you reach bare metal. Then, apply a spray primer to the sanded area.

Once the primer is dry, you can apply the touch-up paint. Use a small brush or the pen applicator to fill in the chipped area with paint, ensuring that it matches the colour of your Jeep. It is important to note that touch-up paint may not always match the original paint colour exactly, so finding the correct colour code is essential. You can usually find the colour code inside the driver's door or door jam, or by searching with your vehicle's VIN.

After applying the touch-up paint, you may want to use a polishing compound to provide a smooth finish. This step will help create a seamless blend between the touched-up area and the surrounding paint, making it less noticeable.

While touch-up paint is a simple and effective solution for small paint chips, it is only a temporary fix. The underlying problem, such as rust or extensive damage, may eventually reappear. Therefore, it is important to monitor the touched-up area and be prepared to seek professional help if further issues arise.

Wax the area

Waxing is an important step in maintaining the paintwork of your Jeep. It is a paint "cleaner" that helps to remove minor scratches and surface oxidation caused by road salt. Regular waxing will prevent future buildup and keep your Jeep looking its best. Here are some detailed instructions and tips for waxing the area after repairing small paint chips with rust:

Wait for the Paint to Cure:

Before waxing, it is crucial to allow the paint to cure completely. The recommended waiting period is around 30 days, but some body shops suggest waiting up to 90 days for solvent-based paint. This waiting period ensures that the paint has fully hardened and allows for outgassing, where solvents used to mix the paint can evaporate.

Prepare the Surface:

Before waxing, ensure that the repaired area is clean and free of any dirt, dust, or debris. Wash the Jeep by hand using mild car wash soap, soft cloths, or sponges, and always wash in the shade to avoid extreme temperatures. Avoid using a pressure washer or automatic car wash on the repaired area, as it may not be durable enough for high-pressure cleaning.

Choose the Right Wax:

Select a high-quality wax designed for automotive use. Avoid using silicone wax, as it can interfere with the paint's curing process and hinder outgassing. Look for waxes specifically formulated for clear coats, as they will enhance the protection and gloss of the repaired area.

Apply the Wax:

Follow the instructions on the wax product you have chosen. Typically, wax is applied in small sections using a soft, clean cloth or sponge. Work in gentle circular motions, ensuring even coverage over the repaired area. Let the wax dry according to the manufacturer's instructions before removing any excess with a clean, soft cloth.

Maintain with Regular Waxing:

To keep your Jeep's paintwork looking its best, establish a regular waxing routine. Depending on the wax product and environmental conditions, you may need to reapply wax every few months. Regular waxing will not only enhance the appearance of your Jeep but also provide ongoing protection against minor scratches, oxidation, and colour fading.

Remember, waxing is an essential step in maintaining the appearance and integrity of your Jeep's paintwork. By following these instructions and incorporating waxing into your vehicle care routine, you can effectively protect and enhance the repaired areas, ensuring your Jeep looks its best for years to come.
