P5 it's the duplicolor graphite color, it threw me off at first too, but it is correct. The directions for the paint just say to use a bug/tar remover on the rim and then do a couple of coats of the graphite, followed by a couple of coats of clearcoat, so no primer needed. I did find that its a pretty high quality spray paint, not a single run with nice even spray strokes. So far I have gone through a regular wash, but I haven't had the chance to go do a real cleaning, I just got back from reno about 2 hours ago. I was thinking about doing the factory grill with the same color, just masking off the mazda symbol- I have a fair amount of it left, so I might mess with it this weekend if the weather is nice.
