Well I must say that leaking has been a non issue at all for me, I’ve had absolutely zero leaks. I can only suggest that you follow Vic’s dam method of wicking that he shows in his introduction videos which you can find below Also make sure you have your coil at least 2mm above the air holes so that any spitting or oozing is minimised, I’m sure you know but just in case you don’t make sure you wick fairly tight through the coil.
Hopefully this will help you have a better experience. Good luck.
Rewicked it again tonight using dam or max vg method in vics video but the same result
Obviously something is wrong with the way I'm doing it but I can't see what. Have a look and tell me what you think
