I looked up some of the other ideas stated on an other post like Diaperene, etc, but they also all had a petroleum base, which I took to mean vaseline! I thought Vaseline was non toxic or else they wouldnt use it on a babys bottom! My question is if it is non toxic for a childs bottom, would it be toxic on a boats bottom! I tried just a little spot of it on my boat and after two weeks the spot is still slick! Who might be in the know?
