I see there is a lot of interest in this! Me, too. I vape pretty much straight VG juice which does not wick as well as the higher PG blends do. All of my used wicks have little burn marks that I am either pulling left or right when I clean or just tossing the bottom wick altogether. But the coils themselves are still in great shape. I know they are cheap to replace, but I would rather use the money for something else, like more tanks, batteries or juices I called all the smoke shops near me and none of them carry 2mm silica wicks, but I found several sources online. I ordered 3 feet for $2.00 which should be here in a few days. Sounds like it might be hard to replace the wick that goes through the coil, though. I have heard the teflon tape works well, but I guess there is a learning curve. I have needle threaders for sewing, wonder if those would thread the wick through the coil without damaging it? Guess I am about to find out! Is it just the tanks with top coils like Halo that tend to burn wicks? I am tipping and swirling to keep the wicks saturated so much I am gonna get carpel tunnel, but it does help a little. I am wide open to any ideas ~ Wampscut, have you tried it yet??
