Antiperspirant CM??

would this help with the sensors placed on the fingers or is it to noticable?

The key to passing a polygraph is to exhibit stronger reactions to the "control" questions than to the relevant questions. It is not clear to me how putting antiperspirant on one's fingertips--which might reduce one's overall rate of perspiration--would help to produce such an outcome.
