Painting and sanding all of the parts that one won't see. But it's all about protecting the composite finish and making it easier to clean. This picture was taken with my phone camera, so the lines are a little distorted. One can see the first coats of Grand Banks Beige in the counter stern and extending forward from bulkhead No. 5. Bulkhead No. 1 still isn't glued in yet as I finish up things in the forepeak that would be more difficult to do later.
