first off, thank you.
dry burns will shorten the life but as many here can attest too and many old timers here, if done properly it can be repeated many times with no issue but of coarse even a good looking coil can pop early..
dont blow on your coil when dry burning.
I think using the butane method retains more of the coils life even though your heating it from an external source but i think that what also preserves it longer.
As to the solvent, yes it does, in 5 minutes the gunk breaks apart and off, then after washing it off a little quick burst just for the kick of it and its good to go, the issue is the solvent was still residuey and takes a long good clean to remove it, very soapy even after they lightened it for me, they did email and say they will attempt 2 more samples, i even sent them a few cartos so they see what i mean by being to residuey, while this is ok for experienced users, we cant sell it if its to residuey, it needs to clean off easy, which i do believe is possible and they will get there.
Blowing on the coil!
That's what probably killed em. I did that with the intentions of blowing any burned residue ash off the coil.
Oh well. Once my baby girl finally gets to come home from the hospital, maybe I'll finally have enough time to take my 2 dead ones apart, rewick and recoil them.
