Ab: Procon Boy Ps-270, 0.2mm. Bought around 2 months ago. I cleaned that thing as well as you could think, incl the nozzle. Regularly. The more time progresses, the shorter the needle exposed at the tip has become. I had this before with my sparmax ab as well. Basically, it is virtually not visible anymore but engulfed by the tip. This is very annoying. I don’t want to push the needle down with force or I will flare the nozzle. However, little exposed needle does not make for any quality spraying. Has anybody encountered something similar? What would you recommend me to do?
