4) Now, you can proceed to painting the engine parts of your classic car. Hang the engine part that you wish to paint from a ceiling rafter with a piece of wire. This makes it possible for you to paint all the surfaces of the engine part at one time.

5) Use the heat resistant primer to spray paint on the part. Applying a single heavy coat of paint will result in runs and drips, and therefore, you should apply a few light coats instead. Wait for the primer to dry. Make sure that you wear a respirator when you are spraying and work in a place that is well-ventilated, because inhaling paint fumes can be detrimental to your health.

7) After the primer has dried, you have to sand the engine part lightly with emory cloth. Use a damp rag to clean the part and let it dry.

8) Then, hang the engine part from the ceiling rafter again and spray heat-resistant engine enamel as the final coat. Similar to applying the primer, spray a few thin coats instead of one heavy coat, and take the necessary measures to protect your health.

9) Let engine enamel cure for at least 24 hours, and then, reinstall the engine part into your classic car.
