so i have a copper vanilla mod. the past week or so my firing button just will not stop backing out on me. every ten minutes i have to take the switch off and tighten down the contact again. i figured it might be because the threads are gunky as i have not polished or cleaned this mod in a while. so yesterday on my day off from work i sat down at my desk and did a very very thorough cleaning of every part of the switch as well as all the contacts. i put everything back together, popped in a fresh battery and!....it won't fire. i sat there for half an hour trying to get it to fire. the only way i can get it to fire is to back out the switch purposely and then press really hard. but this causes the firing button to literally fall out after 5-10 minutes of use. and even when i CAN get it to fire it seems weak and not as hard hitting (i have a .12 dual coil build so it normally vapes like a train). i figured maybe i left behind some polish or something in some of the tighter spots so i took all my contacts and my switch, repolished it and am now letting them soak in hot water. any other suggestions?
