Yeah it's some potent stuff,i used it a couple times and decided it's probably not a good flavor to keep using haha.My sons adv for several months was tfa banana cream,not sure which banana they use in that,but about once a month he would have to replace the plastic bell cap on his rta because they would get etched,then if he kept using the same one a bit longer,it would get cracks all the way through to where juice would slowly ooze through them.He finally decided that wasn't the best thing to be putting in his lungs haha.
I'm glad you mentioned that. I thought Banana Cream was safe and Ripe Banana was the problem. I've been using a lot of BC lately but only in Pro Tanks. Actually the only tanks I have with plastic are Kayfuns. Guess I should be OK with BC if I keep it out of the Kayfun.
Someone posted a list of TFA tank crackers and one on the list was Crème De Menthe. That's my number one flavor and I've kept a Kayfun loaded with it for quite a while. Doesn't seem to be any problem with the tank section yet. I did get a big bag of plastic tank sections from FT for 60c each so if it goes wrong it's not the end of the world.
