Some of my favorite PS tests are those that pit ordinary dime-store products against gold-plated marine-grade stuff. This months propellor antifouling test called to mind an investigation into the antifouling properties of diaper cream that took place many moons ago. Diaper cream contains zinc oxide, a known biocide, but it does not regulate the release of biocides the way bottom paint does. Nevertheless, youll find many bulletin-board posts that recommend diaper cream for depth-sounder transducers, props, and dinghies. My take-away from our 1995 report is that the product worked (sort of) for a limited period, but it is an impractical solution for hulls . . . better to let you read and decide for yourself.
