[C320-list] Hull prep

[JJ Morrison]

Most folks put way too much biocide paint on their bottoms!! Unless you are using a product like VC17 which works well in fresh water there is no need to recoat every year(the VC 17 goes on very thin). My boat has about 1/8" of Micron CSC and I feather the edges and just coat the flaked areas with a West Marine product CPP plus (it was 50% off so couldn't resist) it is compatible with the Micron CSC. As long as I can see bottom coat I estimate that it is working. Using this method I've never had a problem with bottom fouling here in Lake ON.CheersJohnM1999#574
