Turtling !
I'm sorry, "trutling" the boat on the ground does not qualify you as a member in the "turtle Club".......Sounds like you did a good job, I have some small scratches below the water line area that I would like to fill and sand out too, I keep putting it off because its to hard to sit or lay under the boat/trailer and work on it.I might study your suggestions a lttle bit more, sounds pretty good way to work on her.
