The helmet look very good. Fuzz is bad, Fuzz is dry spray. Why buff such a small part. Just put a little more thinner wait like I said between coats, just put enough paint to make it look wet and stop until the next coat. The first coat should be the lightest one 3 coats should work fine. I NEVER have to buff any Motorcycle parts. Now cars are another story. Tattoo
If Im getting fuzz, I can do two things, work a little closer or turn up the pressure a little more? Both would probably do the same thing Im guessing.
Didn't see this before. You're gun should always operate at the SAME pressure (per manual..). If you're getting "fuzz" it's because you're moving too fast, not close enough, or the paint is too thick.
you're not really trying to smooth the finish w/ the paint, you're trying to get good coverage and hope smoothness comes along for the ride. 
once it all starts to look the same and no primer or undercoat remains to be seen, that's when you're done.
a few nice coats of top coat really help to smooth your finish... topcoat is more difficult than paint though... if you don't recoat it when its still fairly wet it gets fuzzy as i like to call it, then you'll have to buff it before recoating again.
still though, i'd rather be buffing the fuzz off (that comment had nothing to do w/ any of our members! 
) than sanding out runs from too thick of a coat(s).
Sorry Heffay, but I have to disagree with what you're saying. If you're shooting paint with a quality gun, and using quality paints, you should NEVER have a "rough" finish. First coat, fifth coat, or even clear. If you are getting "fuzzy" finishes and have to buff it out, it is simply said that you are not throwing down enough paint. That or it is just too thick. It is VERY rare that a professional painter doesn't have to sand and buff a few runs in the clearcoat. The clear is what makes the basecoat really POP!! Without the proper depth, etc in the clear, you will never get the showroom quality finish.
I do agree, however, that once you start to paint, you must finish it all at once.
The paints themselves chemically "bond" together thru the use of thinners/reducers, etc. If you paint the basecoat, wait overnight, then clear, you wont have as good of a bond between paint/clear and in the end, it will not be as durable as it could be.
