Painting small pieces?

First picture in your latest post is of a latch - the mechanical part with moving parts And yours looks pretty much the way it should when finished.

The second picture in your latest post is the safety catch (circled in red - doesn't come into play unless the latch fails so catches the hood) with the loop to the right of the safety catch

By the way - for painted pieces - last step is a thorough wipe down with Brakleen (because of its primary use on brakes it dries with no residue). You can fake the black plating with a good quality flat black paint and then touch it up when it wears.
