The original blue paint on the bottom of our boat has multiple scratches and skuff marks. The boat is kept on the trailer. I have tried to compound the makks with essentially no success. I think I would like to just mask off the flat part of the bottom and brush on an approprite black paint. I don't want the traditional bottom paint for a boat kept in the water, just a good, easy to apply, nice looking paint which will provide some protection and look good. Any recommendations are appreciated. Thanks.
