I use the LPH 400 LV for all my clearing Dave , has a nice wide pattern & the atomization is excellent at 20 psi with trigger fullly pulled .

Some like the Conventional W400lv with the Tulip spray pattern , I have one and the pattern is smaller and its a tad slower for clearing bigger jobs ( I will use it for solid color base coats though). But with that gun you can buy a nozzle, needle and air cap , and tun it into an LPH 400 , which I am going to do .
