Right after we applied the old number 5 - drat! https://www.smartmarine.co.nz/product/37657/no5-plus-antifouling?srsltid=AfmBOoqAfJ91JXZoLGRlPbC46rfKmP5ha-6MWzaCnw2_pnEiCc6WujRc https://www.burnsco.co.nz/altex-no-5-plus-antifouling-4l?srsltid=AfmBOooa9Lcz9kcjZ5D60OOxGkrHNtdJNog_sfnh2pF4bKkPT19PrLBe I just received an interesting reply regarding antifouling colours from Altex. I used the green standard #5 last bottom paint and it looks really nice, I then learned the #5 Plus is available in Green in Australia, but not in NZ... strange? I enquired why and was told.."With antifoul we are restricted by the government agencies that regulate this area the green Antifoul #5+ is an Australian formulation only and has only been authorised for sale in Australia. Unfortunately this product has not been approved for sale in New Zealand." Does that mean the different colours are different formulation? How does one know which colour works best?

How does one know which colour works best? Yes. A few years back i had a tin of blue that was actually green, and it was the best antifoul Ive ever used. Altex refunded me, and once in the water, the paint below the waterline went pale blue after a few months. A little birdie told me that was a faulty manufacturing batch with faaaar too much copper in it, which is what made it green. So it wouldnt surprise me if sea green 5 plus is a superior product, as I think ive already sampled a trial batch! 1 Quote Link to post Share on other sites
