How to Paint Engine Block While in Car
Materials You’ll Need
- Engine paint
- Sandpaper (120-grit and 220-grit)
- Masking tape
- Primer
- Clear coat
- Paintbrush or spray gun
- Safety glasses
- Gloves
- Dust mask
Step-by-Step Instructions
1. Prepare the Engine Block
Start by cleaning the engine block with a degreaser and then sanding it with 120-grit sandpaper to remove any rust or old paint. Once the block is sanded, wipe it down with a damp cloth to remove any dust.
2. Mask Off the Engine Bay
Next, mask off the engine bay with masking tape to protect it from paint overspray. Be sure to cover all exposed surfaces, including the intake manifold, carburetor, and exhaust manifold.
3. Apply Primer
Apply a thin coat of primer to the engine block and allow it to dry completely. Primer helps to create a smooth surface for the paint to adhere to.
4. Paint the Engine Block
Once the primer is dry, you can begin painting the engine block. Use a paintbrush or spray gun to apply a thin, even coat of paint. Allow each coat to dry completely before applying the next.
5. Apply Clear Coat
Once the engine block is painted, apply a clear coat to protect the paint from chipping and fading. Allow the clear coat to dry completely before removing the masking tape.
6. Cure the Paint
Allow the engine block to cure for several days before driving the car. This will give the paint time to fully harden and adhere to the block.
Tips
- Use a high-quality engine paint that is specifically designed for use on metal.
