Step 04. Let everything dry

Prepare the Surface for Painting

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.

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.

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.
