How To Paint An Alternator


While it’s not practical to paint your car for every possible reason, painting your vehicle’s accessories is totally doable! It will depend on whether you are skilled in doing so or if you want to hire someone else to help you out.

By now, you have most likely noticed all of the cars around you with white, powdery-looking passenger door trimmings. This article will show you how to easily re-coat this element onto your own car!

It is very important that before applying any primer, you make sure that the elements being painted have been cleaned thoroughly. This means washing off any previous coats as well as cleaning the surface area carefully.

Once everything has dried, apply some primer using a good quality brush. Make sure to let the primer dry properly before moving onto the next step.

Next, spray several layers of clear coat onto your newly primed element. You can use either acrylic or enamel paints depending on which one matches your style more. Let each layer dry completely before rolling on the final coating.

Your new, beautifully coated element will hang from your car for many miles! Keep an eye out for our other painting tips to learn more about how to care for and maintain your vehicle.

Find your inspiration

Choosing what color alternators you want to paint is an integral part of painting yours. There are several sources from where you can get ideas for which colors to use for your car’s alternator.

You can do it professionally by choosing a shop that specializes in changing out cars’ electrical components. Or, you can pick up some tips online or through social media sites like Instagram.

There are also many aftermarket parts companies with large followings that have lots of pictures and information about different types of painted automotive electrical equipment. By doing research, you will be able to find the perfect match for your vehicle!

Reminder: When painting any kind of panel, like an engine hood or door, apply at least two good coats.

Prepare your canvas

Before you start painting, it is important to make sure you have all of your supplies ready. You will need a piece of cardboard or paper as a work surface, regular paint brushes, a thin brush for cleaning off excess paint, plastic wrap to protect surfaces while washing, and a rag to wipe down any areas like the car body that may get dirty.

In addition to those basic materials, you will also want to prepare some of the components before starting to paint them. These include: your alternator wire, electrical tape, markers, and spray lubricant such as oil or silicone. Make sure to have enough for the whole process!

You do not want to run out halfway through because you did not realize you needed it until then.

Make a plan for your painting

When you are deciding where to start, make a basic plan of action. Decide what area needs most of the attention first! For example, if you notice that one side of the alternator is looking less vibrant than the other, it may be due to poor exposure or moisture getting in and drying out. If so, then focus on those areas first!

Next, determine whether you want to use brushes or a spray can as a source of paint. There are many types of brushes available and experimenting with different ones can help find the perfect match for each type of surface and design goals.

For more professional results, using a compressor-operated airbrush or electronic airbrush is better than a manual pump air brush.

Practice your painting skills

When doing anything with paint, you will need to practice, practice, practice! Painting is a form of artistic expression that requires you use different colors and textures to show how creative you are.

Practice does not mean perfect, it means having fun while experimenting with materials and techniques. There are many ways to learn how to properly use paints and other products so that you can apply them correctly and know what effects they will have.

Some of the most common things people do wrong when trying to paint is using too much or the right amount of product, mixing them incorrectly, applying them in the wrong way, and/or washing their hands before handling the brush and product.

There are several places where you can find beginner painting tutorials online and in books. Many of these teach you the basics of proper painting technique, such as drawing shapes, understanding proportions, and practicing your hand-eye coordination.

Use the proper equipment

When painting your car’s alternator, make sure you have all of the appropriate tools and materials prepared. You do not want to start working on the vehicle until everything is ready!

One thing that can get mixed up when people paint their vehicles’ electrical components are the rollers used to apply the protective coating. Some people use powder-style rollers while others prefer liquid-type rollers. It really comes down to personal preference.

Just remember that if you choose liquid type rollers then you will need to work quickly because they must dry before you can move onto the next part of the process. On the other hand, powder style rollers can be left set aside for several days depending on the thickness of the coat you desire.

Another element to consider when choosing which roller to use is whether or not you like having white marks leftover from rolling the surface coat away. There are professionals who layer many coats on each component to ensure there aren’t any markings left behind.

Know your colors

Choosing your paint color is probably the most important part of painting your car’s alternator. This article will go into more detail about some helpful tips for choosing yours!

1. Matching The Exhaust Pipe Color

It is very common to see cars with white or silver painted exhaust pipes that are done up in matching interior colors. These types of vehicles look really nice and it can be tricky to choose which exterior color goes well with their internal color.

2. Important Components For Painting An Automotive Electrical Device

Just like working with any other body part, there are several key components when painting an electrical device. Make sure you are aware of these before starting!

3. General Tips When Working With Electrcal Devices

This article will go over some general rules when working with automotive electronics. Make sure to take notes as they may save you time and money in the future!

4. What To Look Out For While Installing A New Alternator

In this section, we will talk about what to watch out for while installing a new alternator onto a vehicle.

Know your textures

The second part of painting is adding texture or luster to the metal surface. This can be done with many things, but one of our favorites is using spray paint!

Spray paint comes in different varieties- matte, glossy, flat sheen, etc. A lot of them are designed to work their way up into the coat of protective clear film that covers most metals. Some have trims or decorations on top which help add depth and detail to the piece.

For this project we will be doing both! Once you apply the primer, use bristle brushes (like bistro style hairdryer brushes) to scrape off some of the thick, heavy painted layer to expose the raw metal.

Once it’s almost all gone, dust away any excess powder by running through the washer with water. Add another thin layer of spray paint and let dry for several hours before moving onto the next step.

Clothing stores will usually sell small containers of very light neutral colored paints that match the color of the car’s interior. Use these to lightly cover parts of the alternator you don’t want to risk ruining.

Thin down the heavier colors with some distilled water and leave it overnight to fully set. Repeat this process as needed until the exposed metal looks smooth and polished.

Know your shapes

The second part of this project is defining your colors. You will need to know what shape your alternator sits in before you start painting it!

The shape of most cars’ alternators are either circle, rectangle, or square. A circle alternator goes around a wire that connects the battery to the vehicle electrical system so there is not much room for decoration.

For the other two shapes, they both have the same decorations at the top and bottom but different sides. The rectangular alternator has painted metal side walls and attached wires going up and down the length of the box.

The square alternator has four sides with painted metal pieces and attached wires going upward from each corner. These are some very specific shapes which can be decorated more creatively.

Now that you know the basic shapes, choose how to organize yours according to size and space.
