So, I noticed something today when I attempted to tear down my new Olympos micron for its first deep clean. I found some scratches on the needle that I am confident were not there when I got the airbrush. Then I noticed the inside of the nozzle has some crazy looking grooves running the length of the nozzle. I have seen machining marks in nozzles but this is crazy. Has any one seen this on other equipment and is it beneficial to try to polish out machining marks in general. I have noticed that iwata HP's and old olympos are very smooth inside the nozzles but I have several new Olympos with rough marks that are circular, like most that you would find. This seems on purpose
