I have had copperbot on the hull and keels of my sailing yacht for 2 years and am very pleased with its performance so far. However due to a couple of scrapes along the seabed there are a few patches on the keels where the copperbot has come off and I have now have a few small areas of rusting keel showing what would be the best way the best way to treat these patches (BTW I do not have access to any more copperbot)
