Question about interior paint. Help!

I just had to put together a replacement column from the original one and a donor column for my 85 D150.
I painted it before it went in, as it had the typical "arc" worn bare from past owners apparently having a big key ring hanging while the one that the truck takes was in the ignition, doing it's job.
I had a can of Rust-Oleum satin black here so that's what I used. It's still slightly too shiney. They used dull drab sheen for interiors to eliminate glare and sun spots which can be quite distracting while driving.
