Hi- was wondering if anyone had this issue with coils getting gummed up.Have been rebuildig coils on my Kanger EVOD for about two months now and have been satisfied with the results so far although after even a few hours of vaping the experience goes downhill due to this gummed up goo on the coil.Been building 1.7 to 1.8 ohm coils and using organic cotton and tried Jap cotton wicks.Have used a wide assortment of juices but can't see that one is causing this over another.Any thoughts?
