Rust On New Starter Solution?

The starter was recently rebuilt and while pulling it I noticed the rear part that was not painted black started to surface rust and looks bad, at least to me. Is there some clear coat that can handle the heat that can be put on to avoid the unsightly rust?

 

Some re-builders don't paint the end plate but I always did. Wire brush it and paint.

 

If you don't want black, you can get engine enamel that looks like cast iron.

 

Aluthane. Brush it on, with the starter in place.

The whole thing was painted black? Here it is now.

 

Get some Ospho and dampen a rag and wipe the unfinished metal until all the light rust is gone. Final wipe with a water damped rag. Let it dry, then coat it with the paint of your choice.

I guess black it is.

 

I stripped my Garage Motor and clear coated the whole motor with Rust-oleum Clear Coat, makes the motor look like Iron.
