How does the Eastwood paint compare to SEM Trim Black? Is the Trim Black close to the correct color or should there be more gloss? I've got some of the REM paint and I'm wondering if I should order some of the chassis black.

Eastwood lists Chassis Black(satin and gloss) AND Extreme Chassis Black (satin and gloss) What's the difference? Would a coat of Diamond clear over the Chassis Black be a good idea?
