ive been using these for a little while, and with many different caps. if your using regular or 2x rusto: get the boston fat for sick @$$ flares and fills, nyfat or lego thin for the outline. anything else is not as crisp. HOWEVER if you use the tall rusto proffesionals its difficult to get a good fat spray. the female rusto fat actually sprays the best for the rusto pros from what ive tried. either way its a must have for rustoleum users
if you use rusto, get the pink adapter and 100 of these and youll never use another setup again. fat ASF!!! BEAUTIFUL FLARES!!! perfectly clean donut dot! fattest lines possible on rusto trust me. any other fat caps with the adapter dont work near as well.
