Benefit of Electrical Grease I use a mechanical mod. That aside this can be helpful to those using regulated mods as well. I was sitting here briefly and experiencing some low quality vaping. I had already replaced a coil in one RDA and knew the other RDA was fine as far as coil/s. I checked and tightened the battery cap on each mod, two. These steps taken I figured vaping ought to improve. Vaping did not improve. Well, I thought the next step would be to lube the mods up. This entails putting a dab of Ox-Gard (brand) electrical grease on the firing pin and the leaf spring firing arm. Electrical grease comes in a variety of brand names, No-Ox, Ox-Gard, Rust-Ease and so on. After applying the dab of grease with a cotton swab, I turned the swab around to the dry end and wiped away excess. Then, vaping did indeed see improvement. Electrical grease contains trace amounts of zinc which is highly conductive. This helps to better the flow of current from the battery to the RDA, tank, atomizer. Thought such a benefit warranted notice. So, if you're having a crummy vape next time you might want to consider a dab of electrical grease.
