How do I eliminate the metallic taste on the protank 2? I know it's not the tank because I've washed it and I see burn marks on the tiny rubber piece that surrounds the clearo head (not the cup shaped piece that goes above the wick). Can I just remove it all together or would that cause flooding. Can I replace it with the rubber piece if the clearo fit my T3s since they look the same and doesn't burn? Does Kanger make a replacement piece that is more heat resistant? Or is it because the protank has thick wires on the wick that raise the temperature of the clearo and I have to rebuild it with thinner wires( which I have no idea how to do).
