I don't think WPS primer was ever formulated to be rolled on, just sprayed.  It is tough stuff, and it is true that when finishing our aircraft, we will end up sanding off 90% of the primer applied. That being the fact, I can report only positive experience with the Poly-Fiber Smooth Prime which is water based, is designed to be rolled on, and is also designed to be easily sanded off.  If only I had found this stuff when finishing my wings, I would have saved hundreds of hours of sanding time and many cases of beer.  Buy a quart sample kit and a foam roller from Aircraft Spruce, and try it.  Get the users manual from Poly Fiber (quite extensive and well written) and follow the instructions.  You'll like it.  But you will miss the opportunity for hours of body building exercise.
