What paint to use?
 

I am going to paint my boat. I have tipped Awlgrip and I had good results. This time I want to spray and I think I can, because I pick things up quickly, and I don't want to sand in between coats. I am looking at Awlgrip, PPG, and Imron. I am considering the Imron because I hear it is more user friendly and can be wet sanded easily. I will be painting in the 50-60 degree range. I am looking for advice on caracteristics of the paints and applications, what kind of gun, things like that. I get info from the manufacturers but all of the paints must be the same because they all tell me why thier paint is the one I should use.
