Ahah! Finally got to dive on my prop last week (the one coated with cfp, ) It was badly coated with barnacles after 7 months,I dont know if it would last longer if I dived every 5-6 weeks and cleaned it but that was not the idea of the exercise. I dont think I will use this system again. Maybe ill do a test piece that is slightly illegal, and see how that goes. catch you later .
