eliquids sitting in aluminum is a no no in my opinion, and its clearly tasted using an AVS & AFS also in my opinion. The oxidation process starts almost as soon as that liquid is put in the tank. This is why tanks are going clear and to plastic, I argued this point with Imeo for months and it caused a huge argument between him and I, and he still won't admit it to this day, and I'm glad this post was made outside of the GG forum where it can be openly discussed. I wanted an all clear Delrin type tank and was told by him it couldn't be done and that's when I was like PFFFTT uhm ya it can be. Now today they are coming out and many are producing clear tanks from different plastic type materials, Ego, Oval, Fluxomizers, MapTanks, it's a very hot product right now. Steamhit, I wouldn't vape outta that aluminum tank, and it's the same reason I stopped doing it as well, you taste it, same as I did, it's quite evident that the taste is there and what is happening when you put eliquid in a metal tank, it's a no no, "Oxidation" there are metals that are better then others like medical grade stainless steel, gold, even Nickle is better then Aluminum, but I still don't like the taste of my liquids sitting stored in a metal tank, any metal, it's a good reason also why when you purchase eliquid it comes in a plastic or glass bottle, which both are safe to store liquids in. when it's in your Atty it is there briefly until vaporized. I'm glad someone else realizes this and wasn't afraid to come out and speak there mind on this subject, Thank you for your post Steamhit. I'm sure others will disagree but there are numerous proofs of this pudding if you just read and investigate as well as vape it and taste it.
