Original poster: "by way of Terry Fritz <twftesla-at-uswest-dot-net>" <Leik3-at-aol-dot-com> Hi guys, I've heard a lot of refrences to mineral spirits, mineral oil, and high voltage oil. What I'm really looking for is something to submerge my cap in. I heard that some plain ol' motor oil works good, and also that regular vegtable oil works as well. Any help would be appreciated. Thanks, Dennis
