Dunno Pac....sprayed latex out of FF tips for years. The last thing I would ever spray out of an airless is conversion varnish. The next to thing would be stain. The thing about spraying latex out of a fine finish is you wont have that much material waste and you're able to adjust the fan pattern a little better. Can't think of one time I've used a .015 on base boards, trim, cabinets, doors....just about anything I want a nice smooth finish on.
