Step 03. Cleaning your engine bay

To clean the engine, you can use a degreaser. A degreaser will help you to remove old dust and paints easily. Shake the can before you spray, then just spray it all over your engine bay.

You may wash the toughest areas with a brush while it soaks in. This is highly dependent on the state of your engine bay.

Step 04. Let everything dry

You are done cleaning the toughest dust using a car degreaser but again, use water to wash any dirt left. Once all the dirt is washed away, make sure to dry the component. Let everything dry for a moment so that you can move into the next steps.

Prepare the Surface for Painting

Step 01. Set up your workstation

A workstation is required for painting, and it is preferable to have your station outside. If you can’t work outside, find a well-ventilated, dust-free, and large space where you can leave the engine bay to dry for many hours.

The space should be spacious enough for you to paint the engine compartment from all sides. Remember to cover the surface with a piece of paper or anything else to catch any spilled paint.

Only protecting the ground or floor will not do. You must also protect yourself by using safety goggles and wearing a dust mask.

Step 02. Remove the rust with sandpaper

To prevent rust from spreading over time, it’s vital to scrape out all of it. Make sure you get beyond the rust to the bare metal. If the metal is fully rusted, you’ll need to take your vehicle to a specialist to get it replaced.

Step 03. Remove the old paint

You can’t paint on the old color. You have to rub off the old paint to get a better finishing with new paint. You can use 100-grit sandpaper to scrub out the old painting. Make sure you protect your eyes and faces while doing all the work.

Step 04. Sand the metal you want to paint

Sanding the engine bay is an important step before painting. Sanding helps the new coat of paint to stick to the surface firmly. Sanding the bay will result in the dust; you can use a damp rag to wipe it all off.

Step 05. Cover everything before painting

Check to make sure everything is well covered and that the pipes, cables, and electronics are all covered from paint overspray. Aluminum foil or plastic can be used to wrap them. Adding additional tape to the area will also add to the protection.

Painting Steps of Engine Compartment

Step 01. Apply painter’s tape where you don’t want to paint

You intend to repaint the engine bay. You may use a variety of colors and designs to suit your needs. You can use tape to cover any parts you don’t wish to paint.

Step 02. Painting engine bay with a spray can

For this phase, you’ll need some automotive engine paint. Paint the engine compartment or the brake calipers using a high-temperature engine compartment or brake caliper paint.

Different companies make their paints with different ingredients, so never combine different brands spray together; it may react badly. If you would like the engine bay to shine, go with glossy paint, and if you would like it to be matte, go with matte paint.

Begin by painting the prepped surfaces with two light coats of paint. Allow the first layer to dry completely before applying the second. Apply two more thick layers, let each one dry before moving on to the next.

Step 03. Painting engine bay with brush

If you want to paint with a brush, then you can use foam brushes. They’re made to precisely cover the surface with fewer strokes.

Step 04. Remove the painter’s tape

Once the painting work is done, then take off the painter’s tape. Remove the tape while the color is still wet but avoid cracking the paint and let the paint dry for a few hours.

Step 06. Reinstall all the parts

After all the steps are completed, reassemble all the parts you removed.
