Hmm, not what I wanted to hear. Sick of mine getting completely covered with barnacles in 2 weeks so anti-fouling them (trim-tabs not barnacles) this April.
jeez, the trim tab is nowhere to be seen. In fact the whole boat has been eaten away to reveal a surreal sign saying "image not available" which I imagine must be what happens when something that used to be there gets eaten away?
Well that just goes to show that I can't attach an image! It was not a pretty sight anyway. If you can offer any advice I will have another go.
I have just had an email from International Paints and their advice was to abrade heavily and apply Trilux. I'll try that
