tie a sock around the top of the cup if its an older style syphon feed gun then most likely it is dripping out of the hole on the top and your getting those drops on the bow . The other option is that if your using a gravity feed gun you are not holding the gun paralel to the surface and the paint is drying before it actually hits the surface which will produce a rough bumpy texture . Thats why I am using the roll & roll method on mine much less headaches including overspray .

. You can see my boat in its current state in my resto thread follow the link at the bottom of my post last page or second to last should have todays progress on the paintjob. I have a slight orangepeel but not bad at all considering I am just rolling it on . I roll it on a small area with a fairly heavy stroke then reroll the area with a very light stroke in the same area. You can watch Harbor freight for their gravity fed 20 OZ guns they go onsale for $9.00 all the time . I have half a dozen of them several still in boxes . They do a decent job for a cheap gun certinly not a Sata or Devilbis HVLP but pretty dang good for $10.00 and change with tax LOL.
. You only want to mix a quart at a time then spray it then mix the next quart. You can color sand the last coat if its orange peeled badly but then you will want to machine buff it out and that one can get skeery if you have never done it before . I wouldnt worry about it other than maybe the sides and top cap and even then you will have to be real carefull around the rivets .
