Yes, I understand i will get some blending and i l actually want that so no problem there. I am painting colorados, cascade, and willoleafs of various sizes usually not smaller than #5s. As for air pressue when i drop down below 5psi my brush does not want to shoot the powder real well. I am trying to duplicate a blade color that I am successfull with on a cascade blade which goes from a dark green to yellow chartruse to white and then repeats the chart and green again. I know I am new but im pretty crafty and have some beautifull two tones its really frustrating me. Also I have my booths set up for shooting different colors and I have notice some poeple have a vacum set up ontheres with a filter should I do this to pull away errant powder from my blade? Thank you for your response.
