I did a bad thing and left my Mariner on a mooring buoy on Lake Michigan a past summer. When I pulled it out at the end of the summer - the hull was covered with Zebra Mussles. Not being acquainted with these critters - I wasn't expecting the havoc they played with my hull. I water blasted them off and tried to clean the residue off with some hull cleaner but I wasn't able to clean off everything. I would like to clean up the hull and this time coat it with VC-17 or some other product to keep it looking half way decent and protect it should I put it back in the lake again. Has anyone had experience with cleaning up after something like this - I was amazed at how they quickly overran every inch below the waterline.
