Although I'm sure its not 100% factory correct, I love the SEM Trim Black paint. It sprays really well for a spray can paint. If it's not a 100% resto you're doing than its the way to go.
I orginally painted mine with black base coat and a semi-gloss clear coat out of a paint gun. However I was unhappy with how it came out and ended up re-painting it with the Trim Black.
