HVLP Needle size for Morrells waterborne primer / lacquer ?

[flanajb]

I am spraying Morrells white primer 8005/641 (Waterbourne) and Morrells 362 "Severe Use" Waterbourne Lacquer gloss white (8901/362) and I just wondered what needle size I should use. I have been using the 2mm standard needle with my Earlex spraystation and it seems ok, but a little splattery.

I am aware other forumites use this paint and I am hoping someone who has a lot of knowledge will be able to comment.

Thanks
