ok, im definitly switching to iso because at first this oil smoked good, but now its caking up all kinds of black crap all over my vape coil and causing parts of the coil to not heat up right. I had to soak the coil in alcohol to get the stuff off. It kinda looks and acts like pipe resin after its smoked, it bubbles up and cools rock hard sure its from all the water in the everclear coagilating all that junk.
