Sand and Refinish Aluminum Wheels

When aluminum wheels start showing signs of wear and tear, it’s pretty obvious. You might see scratches, marks from hitting curbs, or spots where the clear coat is coming off. These signs tell you it’s time to do something.

Facing these challenges, doing the refinishing yourself might seem like a good idea. Not only do you get the satisfaction of making your wheels look awesome again, but you also save money compared to going to a professional. If you have the right knowledge and tools, you can turn your tired-looking wheels into shining examples of how cool cars can be.

In this guide, we’ll talk about how to sand and refinish aluminum wheels. We’ll cover the steps you need to take, important safety tips, and what materials you’ll need to make your wheels look great again.

Tools and Materials List

  • Sandpaper of various grits (e.g., 220, 320, 400, 600, 800, 1000)
  • Sanding block or orbital sander
  • Spray bottle with water
  • Mild dish soap
  • Wheel cleaner (optional)
  • Denatured Alcohol
  • Masking tape
  • Polishing compound
  • Microfiber cloths

Wheel Removal and Cleaning

Before you start refinishing your wheels, it’s super important to make sure you remove them safely and get them ready for the makeover.

First things first, you’ve got to jack up the car safely. Check your car manual for the right way to do it because it can be a bit different depending on what kind of car you have. Doing this properly helps prevent accidents and makes it easier to take the wheels off.

Once the car’s up safely, use a lug wrench to take off the lug nuts. Loosen each nut carefully in a star pattern to make sure you’re not putting too much pressure on one part of the wheel.

After you’ve got the lug nuts off, gently take the wheel off the hub. Be careful not to damage anything while you’re doing this.

Now comes the really important part: cleaning the wheels well. Use a mix of mild dish soap and water with a soft brush to scrub off all the dirt, grime, and brake dust stuck to the surface. If there are any really tough spots, you might need to use a special wheel cleaner to get them clean.

Once they’re clean, make sure you dry the wheels completely with clean cloths. Any leftover moisture could mess up the refinishing process and make your wheels look not so great in the end. So take your time and make sure they’re totally dry before you move on to the next step.

Steps to Sanding Aluminum Wheelssand aluminum wheels

Here are the important steps to follow when sanding aluminum wheels:

1. Check for damage: Before you start sanding, look closely at the wheels for any scratches, dents, or places where the paint is coming off. Knowing what needs fixing will help you decide how to sand them.

2. Remove old finish and paint: Once you’ve checked the wheels, it’s time to get rid of the old finish and paint. Depending on how damaged they are, you might need to use chemical strippers, sandblasting, or coarse sandpaper. Make sure you remove all the old finish so the surface is ready for refinishing.

3. Pick the right sanding method: After getting rid of the old finish, choose the best way to sand the wheels. Wet sanding is often the way to go because it’s cleaner and gives you a smoother surface. Start with a coarse sandpaper to deal with any big scratches, then move on to finer grits for a smoother finish.

4. Sand the wheels properly: Make sure you keep the sandpaper or sanding disc flat against the surface and move it evenly. Work on small sections at a time, keeping the surface wet to stop the sandpaper from getting clogged up. Take your time and pay attention to detail to get the wheels nice and smooth.

5. Smooth out any rough spots: Check the wheels regularly for any bits that still aren’t smooth. Use finer sanding sponge to gently get rid of these rough spots, being careful not to take off too much material. Keep checking your progress until you’re happy with how the wheels look.

Refinishing Aluminum Wheels

Here’s a detailed guide on how to refinish aluminum wheels:

1. Choose the right primer and paint: Start by selecting high-quality primer and paint made specifically for aluminum. Pick products that can handle the road and last a long time. Think about what color you want and what kind of finish you prefer.

2. Apply primer: Clean the wheels really well to get rid of any dust or grease. Put on the primer evenly all over the wheels, using smooth strokes. Let the primer dry completely before moving on.

3. Sand the primer: After the primer is dry, lightly sand the surface with fine-grit sandpaper to make it smooth. Focus on any rough spots but be careful not to sand too much. Wipe away any dust before painting.

4. Paint the wheels: Choose a good-quality paint made for aluminum wheels in the color you want. Put the paint on evenly, using smooth strokes. Make sure you keep the same distance and angle to avoid drips or uneven spots. Let each coat dry completely before adding more layers.

5. Add clear coat: Once the paint is completely dry, put on a clear coat to protect the wheels from scratches and the sun. The clear coat makes the wheels look even better and helps the paint last longer. Apply it evenly and let it dry before putting the wheels back on your car.

Polishing and Buffingpolish aluminum wheels

After the painting process is complete, the next step is to polish and buff the wheels to achieve a showroom-worthy shine and flawless finish. Here’s how to execute this crucial stage effectively:

1. Polish the wheels: Use a good aluminum wheel polish and a soft cloth or pad to apply the polish in circular motions. Work on one section at a time to make sure you cover everything. The polish gets rid of any leftover residue, dullness, or oxidation, making your wheels shiny and nice.

2. Buff out imperfections: After polishing, check the wheels for any spots that still don’t look right. If you find any, use a fine-grit polishing compound and a buffing pad to gently get rid of them. Take your time and be careful to make the surface smooth and even.

3. Finish up: Once you’re done polishing and buffing, wipe off any extra polish or compound with a clean cloth. Consider putting on a wheel sealant or wax to protect the wheels and make them even shinier.
