Its a very good primer.
Normally it sprays a little grainy more so than orange peeley.
A lot of 2K primers tend to spray with a slight grain look.
If it is orange peel, I would start by adjusting your fluid adjustment in a couple of turns and you may need another 5 to 10 lbs of air pressure at gun.
If not of that works see if they allow you to add a couple of ounces of urethane reducer.
