Alternative to antifoul paint
Please humour me on this thread.
I'm fed up with how quickly the underside of the boat gets when left at the marina. The constant cleaning of green slime etc.. before the barnacles get hold. Not being dry stacked I was wondering about painting the underside with normal 'emulsion' type paints. I reckon any sacrificial paint will not last long in the salt water environment, which is my point. Anything that attaches to it will come off with the paint.
My test on a gel-coated panel - with white emulsion and a white acrylic undercoat.
Left to dry the emulsion just washes off pretty quickly but the acrylic holds well. I reckon the acrylic would last a few weeks/months shedding its cover over that time. I know just antifoul it with £100 quid tins of copper based stuff, but I didn't want to have this permanent finish. When applied with the acrylic undercoat, the finish did not look bad at all. Being applied at water level and below, not going to see it anyway. Anything to ease the cleaning of hull after 4 weeks in the water would be much appreciated.
