Just a question about the center pin contact on the 91%:
I read this entire thread and saw several concerns about voltage drop. I plan on sticking the extra O-ring in the pin to keep it stable. But with regards to voltage drop across the pin... is it safe to use a chemical that I would not want to ingest on the pin? It seems as if all the airflow is through the hole on the side of the unit, opposed to the bottom feed through the pin I see on all my cartos, clearos, and glassos. I want to use some Stabilant 22 on the threads to promote electron transfer and eliminate voltage drop. I use it in many high speed communication connections at work when I see impedance issues that affect CAN BUS line communications at connectors, and it works exceptionally well. But it is poisonous if ingested. I just want to be sure that I will not be vaping the Stabilant.
Just a couple hours and counting until I get my R91 in my hands. I am excited about giving my first rebuildable a try... and a really nice RBA at that.
Maybe its just me but anything that is "poisonous if ingested" I wouldn't put anywhere near my devices let alone on or near one of my RBA's.
