Hi, looking for some advice on fluid tip size for epoxy and high build primer. Would 1.8 or 2.0mm be best? I am planning on purchasing a Devilbiss FLG5 with 1.4 tip that I can use for clear and basecoat but as only a novice and DIYer I cant afford 2 guns. So far I have used a 1.0mm £10 ebay gun for spraying some alloys etc but I am going to be doing whole panels as I do some restoration work. Learning as I go with help on here and lots of research and enjoy learning a new skill.
