Hi there my first time posting on this forum, looks good, glad I came across it. I have been stuck on copper coat antifouling for both sailing and motor yachts for some time and can highly recommend it. However my stern gear has stripped off its coat after less than a year. (Alloy trim tabs and bronze p brackets). Can anyone recommend a product that works well and stays on these areas and perhaps the shafts and dare I mention props ??
