The SEM color mix code is 4565 for DMR. It is very close, but my opinion is that it is a little lighter. Since the colors of the panels over the entire interior vary a little, you will not notice it unless you are anal like me.
Do not spray SEM when it is humid, it will blush. I had one job turn out pink. I resprayed it on a dry day (few and far between in FL) and it turned out fine.
I wipe the surface quickly with reducer to get it really clean, and pick up any dust. If you dally too long, it will start to grab fibers from the cloth and get fuzzy. Rewiping will usually pick them up. Do not touch the surface with your hands after wiping (wear rubber/nitril gloves).
Your local NAPA paint store may be able to mix and can your paint. Mine does it here, and I do not have to pay for shipping. About $14 per can. You can go on SEM's site, and search for dealers near you. The cost of shipping makes it worthwhile to drive 30 miles for the paint.
