Welcome to ECF and congrats on switching to
vaping. You've gotten some good resources on rayon, I will point out that you don't need to read the entirety of both
threads, although you certainly can if you wish.
I love rayon and it's all I use for a wicking material these days. I just posted my questions on that
thread, and the experts on it got me up and using rayon successfully after about 5 questions and 4 answer posts. So welcome, and by all means research rayon as much as you need to, but you can also ask the questions you have, and you will receive excellent and helpful answers, as well.
Welcome and I hope you enjoy your stay at ECF.
