I notice their main selling point is that there is (upto) 45% copper solids in it. But when downloading the specs of budget antifouls, such as Flag, they also gave 45% solids.
Yes. We applied three coats of Marclear white or light grey in May 2005, in Palma Mallorca, expecting to get at least two seasons out of it. We normally apply 3 litres to hull only (keel is Coppercoated) but they only had 2.5 litre tins so we used two of them. We hauled out at end September in Port Leucate and were pretty disappointed at the levels of fouling. We antifouled as normal the following spring.
