So I haven't seen anything on this subject on this forum yet, sorry if I missed it, but I've now used three different carts on my new 801. Using Italian Creme medium from vapor station, and after 20 to 30 drags I have this weird white stretchy stuff stuck on the bottom half of the outside of the filler. I've pulled it off and have no idea what it is except maybe the inside of the cart itself melted onto it. Anyone experiencing anything similar? Its kinda weird and im a bit worried about it...
