So I bought a gallon of sem hotrod black again, and a hvlp gun, ive painted the hood and the tailgate, and its laying down really well, but im noticing a few stripes like its lighter in one area, can someone tell me how to fix this. Do I need to adjust the way the paint comes out or adjust how much paint is spraying, I know theres a few painters so lemme know, I tried pming daniel but his box is full.
