The only use for oils and scents I've found is to stink up my boat. Every time Ive used smelly jelly I cant buy a bite until I wash that stuff off my lures. frown So I just wash my tackle on a regular basis and if I want scent I'll go with a strip of herring which is usually only for silvers. Every once in awhile a little squirt of WD40 on the hands if Ive gotten gas or grease on them. thumbs
