Well, its painting is easy but also a bit tricky and sometimes time-consuming as well. You have to ensure proper preparation before starting this DIY project. Also, make sure to apply right primer and metal paint for better result.

Thus, to know in detail read the article till the end and then paint your own alloy sports bar.

Can You Paint Alloy Sports Bar?

Painting an alloy sports bar is practical when the surface is properly prepared and the primer and topcoat are compatible with aluminum or the specific alloy used.

Moreover, if you are unaware of the fact that your alloy sports bar may require welding or repair then painting before will go in vain.

So, you have to make sure that the sports bar is ready to paint. Again, you also have to ensure that when the painting process starts you apply the right product in the right way.

How to Paint Alloy Sports Bar?

Refinishing usually involves removing accessories if practical, degreasing, abrading oxidation, priming with an alloy-compatible product, and applying thin durable topcoats.

Required Materials

• Degreasing agent
• Warm water
• Paint stripper
• After wash
• Sandpaper
• Primer
• Paint
• Enamel

Firstly, Prepare the Project Surface

Step – 1: Clean the Alloy Sports Bar

This is the first and foremost thing to do when you are up to paint the alloy bar of your vehicle. Proper cleaning of the surface is the key to a successful painting job.

However, to clean the bar, take a bowl and fill it with warm water. Then add a small amount of degreasing cleaner to the water. Now take a cloth or rag and dip it in the solution.

Then wipe the bar with the rag and remove all dust and debris. After wiping, rinse it with water to decline the remaining residue.

After rinsing, wipe the alloy bar again with a clean and dry rag and let it dry properly. Again, since the alloy sports bar is made of metal, there are chances that it may have rust as well. So, to remove the rust, use a wire brush to scrub over the rusty place after pouring the solution.

When the rust entirely comes off, rinse the surface. Make sure you do not leave even a small dot of rust. It will not allow the paint to adhere to the bar surface.

Step – 2: Remove Old Paint

Now, this step is only applicable when your alloy sports bar has old paint on it. In this case, you do not have to apply the previous step.

Nonetheless, to remove old paint, you can simply use a paint stripper. The product comes with an instruction. In most cases, however, you have to pour the product solution over the bar surface and wait.

After a few minutes, scrape off the paint with a scrapper. To deal with the remaining residue, get an after-wash as well. When you are done rinse the alloy sports bar surface with water and let it dry.

Step – 3: Sand the Bar Surface

When you are done cleaning, sanding is needed. You might need both coarse-grit and fine-grit sandpaper for this purpose. Sandpaper with 80 or 120-grit is good for buffing initially. Later, buff with a sandpaper of about 400-grit.

However, sandpaper grit may vary while adopting the process. You can also take 200 or 300-grit sandpaper to avoid deep gouges. Sanding in this step is necessary. It will allow the primer to adhere to the alloy sports bar properly.

Step – 4: Again, Rinse the Surface

After sanding, rinsing the surface is necessary. Again, it is better to clean with a degreaser. First use the solution to rinse the surface and then again, rinse with clean water. Then let the alloy sports bar air-dry.

Secondly, Priming the Bar Surface

Step – 1: Apply Self-etching Paint Primer

Self-etching primer or any other oxidizing primer is considered best for this purpose. These are manufactured especially for painting on metals. The components in the primer resist rust growth and let the paint stick to the surface properly.

However, before priming cover the areas where you do not want to paint with masking tape. Now, to apply the primer make sure you have placed the vehicle in a well-ventilated place. Then start spraying the primer on the surface evenly.

Do not take the spray too close to the surface. Make a distance of at least 20cm while spraying. Also, make an up-and-down or side-to-side movement. Apply about 2 to 3 layers of even coats of the primer.

Make sure each coat dries properly before applying another coat. Also, after spraying the primer make sure it cures completely.

Lastly, Apply the Paint

Step – 1: Apply Metal Paint

Since you have already sprayed primer, now you can apply any type of paint. However, metal paint is undoubtedly a great option to paint the alloy sports bar of your vehicle.

You can both spray paint or brush on. Just select your favorite color. Whatever method you apply make sure to apply an even coat. For brushing the paint, you can take a paintbrush with synthetic fiber bristles.

Step – 2: Let the Paint Dry

Let the paint dry to touch in between each coat. Generally, 2 to 3 coats of paint are enough. It might take 10 to 15 minutes to achieve dry to touch. When you are done, let the paint cure as well. However, curing might take one to three days.

Step – 3: Apply Enamel

Enamel comes in wider range of finishes including glossy, matte, satin, and others. So, according to your choice, you can select any finish you want. However, a glossy finish makes the defects look more clearly. Yet, if your alloy sports bar does not have any defects then the glossy finish will make it look nice.

Just spray or brush on over the bar surface the way you did while applying primer and paint. Then let the enamel cure as well. When it cures, voila! Your job is done.

How Do You Spray Paint Alloy Sports Bar?

Spray application can produce an even finish on alloy sports bars when the surface is fully prepared and the aerosol or spray system is compatible with the metal.

After shaking the can, it is ready for application. While spraying, always maintain a distance of about 8 inches or 20 cm. Also, try to maintain a certain direction while doing it.

What Kind of Paint Do You Use on an Alloy Bar?

Use primer and paint rated for aluminum or the exact alloy, with corrosion resistance, UV durability, adhesion, and the vehicle's exposure conditions guiding product choice.

Tips for Successful Alloy Sports Bar Painting

• Put on goggles, dust mask, and gloves first.
• Perform the job in a well-ventilated place.
• Do not hurry the process.
• Let the paint dry to touch and cure properly.
• When you are done with the job, remove the masking tapes.

Final Thoughts

A lasting alloy sports-bar finish depends on oxidation removal, metal-compatible primer, thin topcoats, and proper curing rather than simply applying decorative paint.

Since painting the bar is easy, anyone can do this with their desired color. So, by choosing the right paint and process, make your alloy bar look amazing!
