In January I bought a new H&S Silverline with 0.2 Nozzle . And since than I always have problems with thin lines. I use Schmicke paints and some createx , air pressur from 20 to 35 psi , diluting the paint from 1: 1 to 1:5 I tried a mixture of 1 part isopropanol and 3 part water. I tried the 4011 reducer . None of this really helps THe main problem is that there is no konstant reaktion of the brush . Sometimes it works ok , next line I want to spray nothing happens , I pull the trigger a bit more a big splash comes out . I never know what happens next. I bought a new nozzle and needle , but still the same . I have a Sparmax gun and a Toricon , no problem with those, only the Evolution . Any suggestions are welcome .
