This afternoon I cleaned up and painted some of the engine bits and pieces such as the generator mounting bracket, water pump pulley, and thermostat housing outlet. I wanted to return all of these part to their original factory Datsun engine blue color. I bought the paint in an aerosol spray can from Al at Datsun Parts LLC, via ebay.
I started with the generator mounting bracket. I used a wire brush mounted in my drill to remove the old paint and rust from the surface of the steel bracket.
Then I did the same to the cast iron thermostat housing and the water pump pulley.
I used a screen scouring pad to rub all three pieces down with some Metal Prep, which removes residual rust, etches the metal for paint, and dries to leave a rust-inhibiting coating on the part.
Here are all the prepped parts. The pulley has a dull shine, but where some stubborn surface rust remained around the edges you can see the converted rust has turned black.
I primed all three parts using Rustoleum white Clean Metal Primer.
I primed one side and after about a half hour flipped them over to prime the other side.
Then I used Al’s Datsun Engine Blue.
