I spray all Dupont products myself and am a stickler for following the directions, so personally if it were me I would use the 1.5 tip gun. I use a Devilbiss Finishline gun for my primers, it has a 1.8 tip and does well for me, but the primer I use calls for it. Hope this helps some.

The info sheet for the primer I will be using says to use a 1.3-1.6 tip the epoxy primer is thicker than paint, but is just a sealer,--- it is a non-sandable primer and not as thick as the sandable primer (Prima K36- which would require a 1.8 or above) I use the DP40LF all the time and use a 1.4 gravity gun, the gravity feed gun seems to lay it down a little smoother than the HVLP-( some times i will add a bit of DT thinner to make it flow out bettter)- but your results may differ.
