Yes! Mine went on perfectly smooth on some parts as well--same can, same time of day! All I can come up with is the distance you're holding the can away is crucial! I'm doing the 1:72 FM Falcon and I was priming the entire upper and lower hull halves.  After about 3 hrs of wet sanding with 2000 grit paper the rough areas have been smoothed down to where I think I'm OK now.
