Teflon
Dear Bill: Thanks for the letter. We at PYI have tried Teflon with less then good results. After a very short period of time the material would flake off producing a spotty surface. The suppliers of the material suggested that our procedure of degreasing was not sufficient. They also suggested that if we ruffed up the blade surface we may experience better results. Doing each of these did not produce any better results. We did find that it was more difficult to buff out the wheel. One thing I have used here in the great Northwest has been Desitine. (The baby diaper rash ointment.) It is thought that the zinc oxide produces an environment which biological material can not survive on. Of coarse, it does not stay on when the propeller is being used but it works great if I leave my boat for extended periods of time. It also works on dingy bottoms. It’s cheap and can be applied underwater with minimal mess. Hope this helps.Sincerely, Kevin L. Woody
