first time spraying HVLP...trying to figure out tip size. i have a viscosity cup and all, but i was looking it up to see what GF recommends for their water based stains. getting conflicting info.

this is what one page says....0.051(1.3) for HVLP

Recommended Spray Tips for Wood Stains and Top Coats. Fluid tip sizes should be as follows: Compressed air - .040, HVLP - .051, Airless - .009. Recommended Tips for Milk Paint. Compressed air - .050, HVLP - .072, Airless - .013. Air caps should be medium size. Contact your supplier to verify proper tip sizes for your specific equipment

but then it links to this pdf which says stains are .036-.043 (1.1-1.3)

any suggestions?
