The owner of the car had a local company rebuild the three speed overdrive transmission. It was brought back to me for installation back into the car. I did some research on it and found that they were not painted by the factory and left bare metal. It had a lot of surface rust on it and I really didn’t want to install it back all rusty. I didn’t want to sandblast it either at this point since it was a new rebuild. I decided to spray a coat of Zero-Rust on it since you can apply it over rust.

This is the transmission after we sprayed it with red Zero-Rust.

I then mixed up some color to simulate cast iron bare metal.

I matched it to the bare cast iron on the Pexto bead roller that we cleaned with Metal Rescue in a previous post. You can see here that it is a fairly close match.

To give it some detail, I brush painted the heads on the bolts with some black paint.

If I am reading the date code right, this transmission was made on May 2, 1948.
